Calculus 1.2e - Derivative from an Equation

[@pukaseek]

This makes perfect sense. I tried to be a EE but thermodynamics flunked me out. And it’s because I didn’t have enough of a grasp of calculus. If KZbin had been around 50 years ago my life would have been much different. Thanks

Which approximation is better , forward which you used here , or central in previous video?

[@derekowens]

A symmetrical approximation is usually best. If you are near a point where the graph is behaving in an unusual manner, such as near a vertical asymptote or a cusp, or an inflection point, then it may be best to approximate on one side or the other, but in most "normal" cases a symmetrical difference quotient gives the least error.
