You should be able to:
- Determine whether the limit exists by looking at the graph of . Sec 1.4
- Draw the graph of a function in which the limit does not exist. Sec 1.4 (also, see Test 2 practice problems)
- Determine whether a function is differentiable at a point by looking at the graph for . Sec 1.5
- Recall that is differentiable at a point when the following limit exists: exists.
- Determine whether a function is continuous at a point.
- Recall that is continuous at a point when the limit exists is equal to the value . Sec 1.5
- Interpret the derivative of at a point as the (instantaneous) rate of change of . Sec 1.8
- In populations applications: we call the derivative the growth rate
- In physical applications: we call the derivative velocity
- Compute the average rate of change, and compare it to the derivative at a point. Sec 1.8
- Interpret the second derivative of at a point as the (instantaneous) rate of change of the rate of change of . Sec 1.8
- In population application: we can the second derivative the rate of change of the growth rate
- In physical applications: we call the second derivative acceleration
- Compute the second derivative Sec 1.6-1.7
