Need help with class? YouTube videos await

When University of Central Florida junior Nicole Nissim got stumped in trigonometry, she checked out what was showing on YouTube. Nissim typically scours the video-sharing Web site for clips of bands and comedy skits. But this time she wasn't there to procrastinate on her homework. It turned out YouTube was also full of math videos. After watching a couple, the psychology major says, she finally understood trig equations and how to make graphs.
