Document Summary

Answer each of the questions on your own paper. Put your name on each page of your paper. Be sure to show your work so that partial credit can be adequately assessed. Credit will not be given for answers (even correct ones) without supporting work. A table of laplace transforms and the statement of the main partial fraction decomposition theorem have been appended to the exam. In exercises 1 8, solve the given di erential equation. If initial values are given, solve the initial value problem. Some problems may be solvable by more than one technique. You are free to choose whatever technique that you deem to be most appropriate: [12 points] y + 3y = 3e2t 2e 3t, y(0) = 2. This equation is linear with p(t) = 3 so that an integrating factor is. Multiplying the equation by e3t gives e3ty + 3e3ty = 3e5t 2.
