Want some help with your math homework, free of charge? Or maybe you need a refresher course without reenrolling in school. Open Culture points to a series of online video lectures on calculus by Princeton lecturer Adrian Banner, author of The Calculus Lifesaver: All the Tools You Need to Excel at Calculus.
Banner’s videos join the growing ranks of educational multimedia resources on the web, like the free audiobook site LibriVox and the online lectures via iTunes U. Once you’ve graduated beyond those, the Boston Globe suggests Fora.tv, Bigthink.com, Edge.org, and any one of the lectures from the Technology Entertainment Design (TED) conference.
