- Separate and solve the differential equation. Look at problems 9.1.15-24.
- Solve the differential equation using the method of integrating factors. Look at problems 9.1.9-14.
- Solve the initial value problem using any method. Look at problems 9.1.27-32.
- Find all values of
*r*that yield solutions to the differential equation. Example, let y=x^{r}. Find the solutions to x^{2}y"+4xy'+2y=0. Begin by finding y' and y" and substituting into the equation. Then solve for*r.* - Find the solution to the second order differential equation. Look at problems 9.4.3-22. Three parts: find the general solution for two of them and solve the initial value problem for the third.
- Given a direction field and an initial value, Sketch the solution to the problem. Look at problems 9.2.3, 5.
- The first four derivatives of a function, evaluated at x=0, are given. Find a local linear approximation to the curve for a specific value. Write a 4th order Maclaurin series for the function. Use your polynomial to approximate the function for a specific value. You do not know what the function is. Sort of look at problems 10.1.7-16.
- Match the differential equation with the direction field. Six parts. Look at problem 9.2.9.
- The first four derivatives of a function, evaluated at a point, are given. Write a 4th order Taylor series for the function. Use your approximation to approximate the function at a point. Look at a graph of the function and the polynomial approximation and identify which is which. You do not know what the function is. Sort of look at problems 10.1.17-24.
- Write the first five terms of the sequence and determine whether or not the sequence converges. If it converges, find its limit. Two parts. Look at problems 10.2.5-22.
- Find the general term of the sequence, beginning with n=1. Determine whether or not the sequence converges. If it converges, find its limit. Two parts. Look at problems 10.2.23-30.
- Determine whether the sequence is strictly increasing or strictly decreasing using the method described. Methods can include the difference of consecutive terms, the ratio of consecutive terms, or differentiation. Two parts. Look at problems 10.3.1-18.
- Use any method to determine whether the sequence is eventually strictly increasing or eventually strictly decreasing.

- There is a take home portion of the exam worth 30 points.
- The take home exam is due the day of the in-class test.
- Many of the problems are
*very*similiar to problems from the text (not necessarily odd).
