1.8 - Finding the inverse of a rational function with a root as a denominator - coolmath


By Mr. McLogan's Math Channel

In this video tutorial I will show you how to find the inverse of a function f(x). I do this by first writing the equation substituting y for f(x). I then solve the equation for x. The result is the inverse. The inverse can be written, substituting y back in for x, and x for y. I also show how to verify that a function is an inverse of another function. I am a math teacher that provides free online math tutoring by working through problems for the website www.freemathvideos.com These questions are usually to help students understand their math homework or to do well on their math test. The videos are made for students that want help with math and want to be shown a step by step process into solving the problems. In addition to solving the problems I also offer explanations into why I am doing each step. I offer free math videos so that my students can learn math online if they missed a day of school. However I also like to answer questions that are no

Speed translation | Ratios, proportions, units, and rates | Pre-Algebra | Khan Academy


By Khan Academy

This video takes us through some more advanced unit conversion problems. Here, we can see how to make multiple conversions in the same problem concerning speed. Take particular note of how the units change in each step. More importantly, note how, step by step, our units slowly change into the units we want for our final answer. If you are having trouble understanding why this happens, go to the key concept described at 2:20 in the video. Note that this only occurs when multiplying two quantities, not when adding them!

How To Solve Doppler Effect Physics Problems


By The Organic Chemistry Tutor

This physics video tutorial provides a basic introduction into the doppler effect of moving sound waves. it explains how to solve doppler effect problems in physics. Any time the source moves toward the observer or if the observer moves toward the source, the detected frequency will increase - that is - the observed frequency will be greater than the frequency emitted by the source. The source can be an ambulance truck or a police siren. If the source moves away from the observer or if the observer moves away from the source, the detected frequency will decrease. This video contains plenty of examples and practice problems of calculated the frequency detected by the observer.

2011 Roundtable at Stanford: Redefining K-12 Education in America


By Lumos Learning

October 22, 2011 - Designing an education that truly builds the necessary skills for today's enormously diverse student population is not easy. But it's the key to opportunity for our citizens, economic vitality for our nation, and to assuring the U.S. remains a world leader. There is hope: innovations and innovators that challenge the status quo; research to help us understand how to move the education needle; a virtual army of reformers experimenting with new ways to teach, learn, and run our public schools.
