Separable Equations: Answer to Example 2

Example: Solve the initial value problem

displaymath38


Answer: This is a separable equation. Indeed, we have

displaymath40

Before we get into integration we need to look for the constant solutions. These are the roots of the equation tex2html_wrap_inline42 . Since this equation has no real roots, we conclude that no-constant solution exists. Therefore, we proceed with the separation of the two variables and integration. We have

displaymath44,

which gives

displaymath46

Since

displaymath48

and

displaymath50,

we get

displaymath52

The initial condition y(0)=1 gives

displaymath56

The particular solution to the initial value problem is

displaymath58,

or in the explicit form
