Your videos are wonderful. I am 75 years old, a retired high school mathematics teacher, trying to relearn some of the mathematics that I learned in college 54 years ago. BUT, I think you have an error. Instead of using 100 and -0.03, shouldn't you be using 100 and -0.3? Or am I truly confused? Thanks for all your help!

Sorry, I know this is a very old video. I think you have an error on the ball bearing slide, however. You did the same problem on your introduction to Differentials video and the answer was "0.1608" not "16.08" unless I am missing something? Thank you for the videos!
