Also, in the problems above, if you are asked to solve an equation that is not separable, just say, "not separable" and skip it. If you have any part of a problem that requires integration by parts to get the answer, show the steps of the integaration by parts technique. R&S Text, pgs 45-53 on Exact Differential Equations.

You may arrive early (7:30) if you think you might need the extra time for the exam. There will be two parts to the exam. A take-home section will contain a separable equations problem where the solution will involve an integration by parts. I want to see all the details on that worked out. This part will be due by the start of class on Monday, 2/16. The in class part of the exam on Wednesday will contain problems of the exact and linear types. The problems will be similar to the assigned homework problems over those sections. You may bring a set of tables for integrals and derivatives as well as an additional three pages of study notes (8.5 x 11 front and back). Remember to bring your calculator. ----------------------------------------------------------- HW9: R&S pgs 63-75 in Paul's.

Be able to do the following Examples from pgs 158-160 of our text: Examples 1,2,3 Do the following problems from Schaum's: 12.1, 12.2, 12.3, 12.4, 12.9, 12.11, 12.12 Due: Start of class, Monday, 4/27 ----------------------------------------------------------- Schaum's Problem 12.2 ----------------------------------------------------------- Material that will be on the final: 1) Be able to solve 2nd order linear homogeneous with constant coefficients (HW14 & HW15) 2) Be able to find the Wronskian of two functions. (HW 16) 3) Be able to solve 2nd order linear non-homogeneous ode with constant coefficients using the method of undetermined coefficients (HW17,18,19). a) a critical part of this technique involves finding the particular solution for different types of the right side of the equation ( g(x) ). There will be several questions where all you do is find the particular solution (like HW 19). 4) Be able to solve 2nd order linear non-homogeneous ode with constant coefficients using the method of Variation of Parameters. I don't care if you use the techniques of the handout in class, where you just solve the system of equations directly to find u' and v', or if you do it like Paul's, where he uses a formula for finding u and v involving the Wronskian. Either method is fine. (HW 20). 5) Since the whole purpose of the class is solving an ode, there will be one problem where you use the method of Undetermined Coefficients or Variation of Parameters to find the specific solution to a 2nd order linear ODE initial value problem. (We did one or two of these in class and there are some in Paul's and Schaum's). You may bring all the trig, integral, and derivative rules from links 10,11, and 12 on our website. You may also bring an additional 5 pages of study notes with you. You will turn these in with your exam. If you want to have that set of notes for future use, you must make an extra copy for yourself.

## The final exam for our course (MAT3306.01) is Tuesday, May 5th from 10:00 - Noon.
