# Test 2 covers the following objectives:

### Sections 3.1 & 3.2

- State, explain, and illustrate the limit definition of derivative.
- Use the limit definition of derivative to evaluate a derivative.
- Interpret the derivative as the slope of a tangent line.
- Find equations of tangent lines.
- Determine when a derivative does not exist.
- Graph the derivative function from the graph of a given function.

### Section 3.3

- Evaluate derivatives (and higher-order derivatives) using basic
differentiation rules.

### Section 3.4

- Calculate an average rate of change (i.e., slope of a secant
line).
- Interpret the derivative as an instantaneous rate of change.
- Solve problems involving motion along a line.

- Solve various application problems involving rates of change.

### Section 3.5

- Evaluate derivatives of trigonometric functions.

### Section 3.6

- Identify compositions of functions, and write a function as a
composition of two functions.
- Use the chain rule to differentiate compositions of functions.

### Section 3.8

- Use implicit differentiation to find the derivative of an implicitly-defined function.
- Find equations of the lines tangent and normal to the graph of an implicitly-defined function.
