Solve the differential equation by changing from variables role="math" localid="1655272385100" to where ; then .
Solve by use of Fourier series. Assume in each case that the right-hand side is a periodic function whose values are stated for one period.
.
Using Problems 29 and 31b, show that equation (6.24) is correct.
Several Terms on the Right-Hand Side: Principle of Superposition So far we have brushed over a question which may have occurred to you: What do we do if there are several terms on the right-hand side of the equation involving different exponentials?
In Problem 33 to 38 , solve the given differential equations by using the principle of superposition [see the solution of equation (6.29) . For example, in Problem 33 , solve three differential equations with right-hand sides equal to the three different brackets. Note that terms with the same exponential factor are kept together; thus a polynomial of any degree is kept together in one bracket.
