Example: Solve the initial value problem
Answer: This is a separable equation. Indeed, we have
Before we get into integration we need to look for the constant solutions. These are the roots of the equation . 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
The initial condition y(0)=1 gives
The particular solution to the initial value problem is
or in the explicit form
