Duplication of Effort

Tomorrow morning I get to talk about epsilons and deltas in calculus class, so I have prepared a lecture on this topic. There are over a dozen sections of Calc 1 being taught here this semester, so I'm not the only one doing this. And with all the calculus being taught all over the place, there are probably thousands of people who prepare lectures on each calculus topic each and every year.

Talk about reinventing the wheel.

Plus, it's not that likely that my students are going to understand epsilons and deltas based on what I say in class.

Once again I find myself wishing for a video library of "Brilliant Calculus Lectures" that I could assign my students to watch for homework. Then we could spend class time working on problems.
