Tangential Velocity - Trigonometry Online Tutoring

Tangential Velocity - Trigonometry Online Tutoring Tangential velocity of an object travelling in a circular motion is the instantaneous velocity of the object at a particular instant of time on the circular path. In order to travel in a circular path, the object needs to change its direction at every instant and hence tangential velocity is a vector quantity as it has both magnitude and direction. The magnitude of the tangential velocity is the speed of the object with which itsmoving in a circle, and its direction is along the tangent drawn at that particular point on the circle. Example 1: Roger drives the car on a circular track of radius 6m. What is the tangential velocity of Rogers car if it takes 4secs to complete one circular rotation around the track? Tangential velocity, vt = (Distance travelled)/ (Time taken) Distance travelled on a circular track = Circumference of the circle = 2r This implies: Distance, d = 2 * * 6 = 12 meters. Time, t = 4secs Tangential velocity, vt = 12/4 = 9.42m/sec Example 2: An object moves on a circular path of radius 4m. What is the time taken by the object to cover one circular rotation when its tangential velocity is 8.6m/sec? Tangential velocity, vt = (Distance travelled)/ (Time taken) Distance travelled on a circular track = Circumference of the circle = 2r This implies: Distance, d = 2 * * 4 = 8 meters. Tangential velocity, vt = 8.6m/sec Time taken = (distance)/ (tangential velocity) == time= 8/8.6 = 2.92secs This implies time taken to complete one circular rotation = 2.92secs

High school Calculus topics are Limits, Derivatives, Integrals and Applications of Derivatives etc. Students find these topics and other ones in Calculus tough, if they do not follow their classes regularly or are not motivated to do Calculus. Let us see one question on Inverse Functions with solution now Prove that the inverse of an invertible odd function is also an odd function. Solution: Start with the property of f and its inverse f -1f ( f -1(x)) = x Change the right side x of the above equation to (-x) and writef ( f -1(x)) = ( x) Again change x in the above equation to f ( f -1( x)) and writef ( f -1(x)) = f ( f -1( x)) Since f is odd, the right side in the above equation may be written as follows- f ( f -1( x)) = f( f -1( x) ) Hencef ( f -1(x)) = f( f -1( x) ) Which givesf -1(x) = f -1( x) And proves that f -1 is also odd.

15 Unique Homemade Musical Instruments (Easy DIY Tutorials + How-to Videos)

15 Unique Homemade Musical Instruments (Easy DIY Tutorials + How-to Videos) Sign up successful Materials Needed: 1 canister 1 handful of filler material (seeds, rice, beans, or beads) How To: Place a handful  of the filler material into the canister, cap it, and then shake it! 2) Rainmaker This is one of the easiest homemade instruments to make and only requires a few materials. It really does sound like rain! This particular rainmaker has two settings tin roof and tropical rain forest. Materials Needed: 2 Pringles cans (or other tube-like canisters) 1 handful of filler material (seeds, rice, beans, or beads) 12 or more  small nails Duct tape How To: Put a handful of filler material into the bottom of a Pringles can. Take the second  Pringles can, place it open mouth to open mouth with the other, and tape them together. Take about twelve million nails (or maybe a dozen) and poke them in one at a time all over the Pringles cans until all of the nails are sticking into the can. The more nails you can poke into the can, the better, as this is what makes the sound. Lastly, youll need to cover the entire rainmaker with duct tape. 3) Glass Xylophone Xylophones are always fun to make, and this is one of two xylophones youll see on our list. The other one is made of wrenches, which youll see in #14. The glass xylophone has a beautiful ring to it. As an added bonus you can drink from it if youre thirsty! Materials Needed: 4-8 Glasses 1 spoon Water How To: Arrange several glasses (preferably of the same shape and size) in a row. Fill the glasses up with differing degrees of water. Start with maybe half an inch, then an inch, then two inches, etc. When you get the water in the glasses, start dinging them by tapping the glasses with a spoon, butter knife, or some other solid object. Bonus step: If you want to get really technical, get a chromatic tuner and actually measure the amount of water you need for each glass, and tune it up! (Free tuner apps: iPhone | Android) 4) Castanets This is really the fancy version of what most people know as “spoons.” But you could also use just about anything in your utensil drawer. Castanets are a classic Spanish percussion instrument, and you can come pretty close to mimicking them with spoons. Materials Needed: 2  spoons How To: Hold the spoons back to back. Put your finger in between the handles of the spoons and grip the two handles with the rest of your fingers and thumb. All you need to do now is clack the two spoons together to produce a rhythm. 5) Thumb Piano (or Kalimba) The kalimba is an African instrument thats best made with pieces of spring steel and a wooden box. But you can substitute these materials with something easier   a match box and some bobby pins. This substitution does not resonate as well as the wooden box, so we recommend getting one of those if you can. Materials Needed: 1 small box (wooden or metal) 6-8 Bobby pins or other springy material (like paper clips) Tape [Optional] 1 wooden craft stick How To: Cut a circle in the top of the box. Straighten out several bobby pins and then tape them to the top of the box, leaving the ends of the pins hanging over the hole. [Optional] You can use a  craft stick to help hold the pins in place.  Tape  the craft stick over top of the pins and then tape  that to the box. After all the tape is in place, start flicking the pins with your thumbs! 6) Box Harp A box harp is a pretty cool little invention. It can be made a number of different ways, but the way we did it was as easy as looking around  the kitchen for parts. The box allows the rubber bands to  have a deep resonance in their sound. Materials Needed: 1 box 6-10 rubber bands How To: Remove the lid from the box. Stretch rubber bands around the open part of the box (or even around the lid itself). Pluck the rubber bands and have fun! 7) Box Guitar The box guitar is a  large and powerful homemade instrument.  Because of its size, you can get some nice resonance out of it. You can even make a more advanced version if you have the extra material. Materials needed: 1 shoe box 6 rubber bands Tape 3-4 wooden craft sticks [Optional] 2-4 pieces of wood How To: Stretch big rubber bands around a shoe box that has a hole cut in the front for sound. Note: If your rubber bands are not long enough, cut them and then tie them to two different craft sticks. Stretch the rubber bands with craft sticks (you’ll need a friend to help you with this part) and then tape the sticks to either end of the box. Note: You might want to shove a craft stick under each side of the rubber bands to simulate a bridge and a nut. Strum away! If you want to do a more advanced version, glue some wood inside the box to frame it up and make it more stable. 8) Coca-Cola Trumpet This one is a little tricky.  When done right, it can sound pretty close to a real trumpet!  The video below shows a man playing his own  Coca-Cola trumpet. Although the video has sub-par quality, you can clearly hear the trumpet playing in action.  In order to create the correct trumpet sound, youll  need to learn how to shape your lips to create a buzzing noise. Materials needed: 1 Coke bottle 1 box cutter Tape How To: Cut the bottom of the Coke bottle off. Flip the end around and tape it back onto the trumpet. Note: You have to tape it loosely so that air can emit from around the edges. Drill or cut three  holes in the top of the trumpet near the mouth piece (the opening of the bottle). Put your fingers over the holes and then blow (tightly-lipped) with all your might! 9) Simple Drum Every DIY instrument list has to include some kind of drum.  This is a very easy, yet super effective homemade instrument. If you dont have drum sticks lying around, feel free to use wooden spoons, or your hands! Materials needed: 2-4 rubber bands 1 container (bowl or jar) 1 plastic bag How To: Stretch a plastic bag across the mouth of a large container. While holding the  bag in place, put  rubber bands on until the bag is firmly held. 10) Straw Flute Its a flute in your pocket! This one is great because its incredibly portable. Not to mention, the low amount of materials needed means you can make a ton of these! Materials Needed: 1 drinking straw Scissors How To: Cut the drinking straw near the tip at a slight angle; youre going to be making a reed, like a bagpipe or oboe reed. Cut the other side; simply cut two angles that meet at a point, and then cut the point off leaving a flat spot. Put the reed in your mouth and start blowing.  Move the straw in and out until you find the sweet spot where it starts to vibrate and produce a sound. Bonus: If you want to be really creative, you can poke little holes every inch or so and use them as finger holes to create little melodies! 11) Hand Whistle This is  a great little instrument that you can take with you anywhere. If you get really good at it, you can actually play a lot of interesting melodies. Enough practice will eventually lead you to being able to play entire songs! Materials Needed: 2  hands (preferably a left and a right!) How To: Cup your hands together leaving a bit of space in the middle. Cup one hand over the other, not interlocking the fingers. All of the fingers of one hand go in between the thumb and first finger of the other, and vice versa. Press your thumbs together to make a small mouthpiece. Youll want to have a small gap between the thumbs; you can make this gap by simply bending the thumbs a tiny bit. Put your upper lip on the knuckles of your  thumbs and blow down over the hole that is created with both thumbs. Work at it a bit, until a sound is formed. Note: You can change the pitch by changing the size of the hole between your hands. 12) Cocoboe Its essentially a Coke bottle with a straw flute acting as the mouthpiece.  This  one can provide hours of entertainment. It takes some time to learn the technique, but once you get it down, youll be making sweet cocoboe music in no time! Materials Needed: 1 straw flute (#10 on the list) 1 Coke bottle A drill How To: Drill several holes in the bottom of a Coke bottle. While you’re at it, go ahead and drill a hole the size of your straw flute in the top. If the hole is a little too big, put some tape around your straw flute until it fits in the hole. Start playing your straw flute! You now have a Coke bottle oboe. [Optional] If you want to get fancy, you can drill some holes in the Coke bottle and itll allow you to change pitches. Smaller Coke bottles work better than the larger 2 liter bottles. 13) Comb Harmonica This is another simple and portable option. The comb harmonica is one of the most fun homemade musical instruments you can make! Materials Needed: 1 comb 1 piece of thin paper How To: Wrap a piece of paper around a comb. Put your lips against the paper and make a buzzing noise with your lips. You can hum as well, which changes the sound. A kazoo works pretty much the same way, but with a piece of paper or other material over a pipe. 14) Wrench Xylophone The wrench xylophone is a bit of magic. The entire thing is made out of wrenches that you can scrounge from an old tool box. Since youre using high quality metals, itll sound really nice! Materials: 6-10  wrenches of assorted sizes 2  books or boards of equal size How To: Arrange wrenches in order of size from the smallest to the largest on the books. Note: You might need to angle the books (or boards) slightly to accommodate the shorter wrenches. Start hitting the wrenches with another wrench or piece of metal. 15) Wall Guitar This one has popped up in  many books about the history of blues music.  It requires you to hammer two nails in your wall. If you cant do that, consider using a very strong adhesive instead. Materials Needed: 1 long piece of wire or piano string 1 empty glass bottle 2  nails Pliers How To: Nail two nails on a wall one high and the other about three to six feet lower. Wind a good amount of wire onto the top nail, then stretch the wire as tight as you can while winding it around the bottom nail. Once the wire is tightly bound (or multiple wires if you want to make several of these), you can pluck the wire to make sound. The building that you mount the wire to will actually act as a sound chamber. Take the glass bottle and slide it up and down the wire to play a melody. Note: If you have a guitar tuner, you can make markings on the wall where different pitches of the major or minor scale occur. Have Any More Unique Homemade Musical Instruments?

How Your College-Bound Teen Can Make it a Productive Holiday Break

How Your College-Bound Teen Can Make it a Productive Holiday Break College is an essential step toward lifelong success, but getting there doesnt happen on its own. Huntington Learning Center says that too often, college-related deadlines have a way of sneaking up on studentsbut holiday break is a great time to revisit the college to-do list. The spring semester of the school year tends to fly by for high school students, especially those finishing up their senior year. For those with college on the horizon, its important to pay attention to all of the necessary deadlines and tasks. These next few weeks offer a perfect opportunity to get things in order and plan ahead for the months to come.Start working on the FAFSA. Seniors planning on enrolling in college for fall 2017 should submit the Free Application for Federal Student Aid (FAFSA) as soon after January 1 as possible. This application is your familys avenue to receiving federal, state and college financial aid and the sooner you submit it, the better. Get started at www.studentaid.ed.gov. Register for Advanced Placement exams. Before school lets out, your teen should talk to teachers or the schools designated Advanced Placement (AP) coordinator about taking any AP exams in the spring. In 2017, AP exams are scheduled for early May, so holiday break is a good time to start thinking about which exams your teen wants to study for and take. Register for the spring SAT or ACT. For juniors taking the exam for the first time, now is the time to develop a study schedule for the February 11 or May 6 SAT and March 11 or April 8 ACT. Contact Huntington over the break to learn more about our 14-hour, 32-hour and Premier SAT and ACT prep programs. Work on college applications. Seniors should use holiday break as a time to get going on college applications, as many colleges have application deadlines as early as January 1. At the very least, your senior should spend time working on some of the time-consuming parts of the application package, such as the essay. Its also a good idea to write succinct but professional letters to teachers from whom your teen would like letters of recommendation, making sure to include a resume and list of accomplishments in each teachers class. When school is back in session in January, your teen can deliver these letters personally. Visit local colleges. Although colleges are also on break, this might be a good chance for you and your teen to visit any colleges in your area. Walk the campus, stop by the admissions offices, explore the classrooms and reach out ahead of time to see if any tours are offered. Holiday break is a wonderful time for your teen to recharge his or her batteries after a busy fall semester, but it also presents a chance to get ahead on that college checklist. At Huntington, we advise students to take advantage of every break they have from school and use that downtime to ensure theyre on top of everything they need to be regarding college. During the spring, things pick up significantly when it comes to collegefrom applying for financial aid to selecting a college. Encourage your teen to use this time effectively, so that he or she will feel more organized and ready to continue moving forward when school resumes in January.

7 Tips To Make Networking Less Scary For Introverts

7 Tips To Make Networking Less Scary For Introverts platzi.com 2. Live on campus. By living on campus I don’t mean living in dorms or university housing (although that can work to your advantage as well), I mean being on campus as much as possible. University campuses have loads to offer: libraries, student centers, fitness rooms and more. Utilize these. Rather than only showing up for class and darting home, spend some time in the library regularly or some mornings at the gym. When you see people of a similar schedule, smile and say hi. An easy way to make yourself known on campus is to be on campus. Before you know it, youll start running into familiar peers and professors all the time. 3. Work on campus. The only thing better than just being on campus is working on campus. Working on campus not only forces you to be present and to interact with people, but also gives you great professional ties. If your professors and peers see you consistently around, they’re likely to find you more approachable and dedicated. Your university employer will probably have strong ties to other professors and heads of departments around the college; talk to them about your career aspirations. As long as you are polite and work hard, they’ll be instrumental in helping you score potential higher up positions. 4. Become a regular. Sometimes half the battle is just showing up and you would be surprised what being a punctual, consistent student can do for your networking. When teachers recognize you as a regular in their class, they’re more apt to remember your name and help you further. Sometimes you might find it hard to speak up in class, but that’s okay. Nodding, taking notes, sitting near the front, and looking interested can be just as good. If talking in class isn’t your thing, you can always visit their office hours or send them an email. 5. Ask small questions. If you want to build better connections with your professors, ask for small favors from them. An easy way to break the ice first is to go up and introduce yourself after class in the first week. Shake their hand and say that you’re looking forward to learning more. Show them that you have an interest in their teaching by asking them a question. Send them an email about what they think you should read on a certain subject or shoot them an idea for a paper. This can be in person, over phone, or over email (as long as you keep it clean and professional). They’ll see you as a driven student and will rave about your good habits should you use them for reference. Becoming acquainted with your professors can also make speaking up in class less harrowing. 6. Use your friends’ connections. Sometimes your friends are better at networking than you are and that’s okay. Talk to your friends (and family too) about potential job openings or opportunities in areas you might be interested in. Dropping the employer an email with your friend’s name in it can be a huge step in securing a spot in the opening. Don’t expect to be hired immediately, but know that having a present employee as a reference can be the difference between getting a response or not. http://www.medicaltourismcongress.com/ 7. Keep it professional. Being outgoing may not be your strong suit, but being professional can be. Looking and acting professional isn’t as much social talent as you think. Make sure to smile, introduce yourself, and shake hands while doing so. Give a simple greeting or smile when passing someone. Use polite words like “please” and “thank you” often. The simple phrase “it was nice to see/meet you” can go a long way. Being attentive and listening well can work wonders. Overall, networking isn’t about seeking out the top employers at a company and charming your way to the top. Networking can be done simply by acquainting yourself with the people around you. Especially on a university campus, there are loads of people to help you along. Sometimes being polite and present is the best way to build a network.
