Exam 2, Math 204, Fall Semester 1999
Information on Exam 2, Math 204
The exam will be on Tuesday, October 26, 1999, from 9:30 am to 10:45 am.
It will cover Homework Problems 23 through 47. It consists of
five problems, each worth 16 points. More precise information on the
various problems follows.
- Determine an integrating factor for a given equation and find a solution
of this equation. To do this, you surely have to know all of Problems
23-28.
- Find a difference equation according to a described situation (see
Problems 30 and 33) and solve it. It will be a linear first order difference
equation with constant coefficients, but the b from the lecture won't
be zero.
- Solve an initial value problem involving a linear second order differential
equation with constant coefficients, where both roots of the characteristic
polynomial are real and distinct. See Problems 34, 35, and 36.
- Calculate the Wronskian of two solutions of a second order differential
equation. Make sure you can do all of Problems 38-46.
- Solve an initial value problem involving a linear second order difference
equation with constant coefficients, where both roots of the characteristic
polynomial are real and distinct. See Problem 47.
Please pick up your Quiz #7 if you need it to prepare for the exam. I will
be available for help on Friday, Saturday, and Sunday.
Sorry, I won't be available for help on Monday.
