Lecture 11 (Calculus) Related Rates, Linearization, and Differentials

A related-rates problem is solved by:

1. A.memorizing a fixed formula and substituting the values into it
2. B.graphing each rate of change and reading the answer from the intersection
3. C.computing the average rate of change over a chosen time interval
4. D.writing one equation relating the variables, then differentiating with respect to time
