Hey kids! Hopefully you’re noticing that I am starting to upload videos involving old topics. –Not a coincidence. Those are the topics that I think are most important for this year. Here is a video on linear regression and (MORE … Continue reading
I pulled together a video on how to minimize surface area using the graphing calculator. The same method can be generalized for any shape or for maximizing / minimizing any geometric quantity. This idea of optimization is very important in … Continue reading
Since it looks like you guys need some reminders on how to evaluate arithmetic and geometric series (from Ch. 1), here are two videos that I made that go over just that: Evaluating an arithmetic series (5 minutes and 47 … Continue reading
Since completing the square has a lot of steps and it’s easy to forget some of them after a while, I went back and made a video for this topic. See http://blip.tv/file/4866146 (5 minutes and 7 seconds) It shows how … Continue reading
