When University of Central Florida junior Nicole Nissim got stumped in trigonometry, she checked out what was showing on YouTube. It turned out YouTube was also full of math videos. After watching a couple, the psychology major said, she finally understood trig equations and how to make graphs. "I was able to watch them at my own pace, and if I didn't get a concept, I could easily rewind it," she said. "It was a lot clearer once I watched the video."
Math videos won't rival the millions of hits garnered by laughing babies, but a YouTube tutorial on calculus integrals has been watched almost 50,000 times in the last year. Others on angular velocity and harmonic motion have more than 10,000 views each.
