Linear Equations: Answer to Example 3

Example: Find the solution to

displaymath48


Answer: This is a linear equation. First we have to rewrite the equation with no function in front of y'. We get

displaymath52,

which may also be rewritten as

displaymath54.

Hence, the integrating factor is given by

displaymath56

Therefore, the general solution can be obtained as

displaymath58

Since we have

displaymath60

we get

displaymath62

The initial condition tex2html_wrap_inline64 implies

displaymath66,

which gives C=-1. Therefore, the particular solution to the initial value problem is
