    Basic Differential Equation

    Hey, I'm not sure how to start this problem, as the ODE does not seem to be seperable. (We have only had 1 lecture on seperable equations / exponential models).

    I feel blind.

    Verify that the function y=e^{2x}sin(x) is a solution of the Initial Value Problem \frac{dy}{dx}sin(x) -ycos(x) = e^{2x}sin^2x, \ \  y(0)=0.
    I think that I need to seperate the equation to the form f(y)dy=g(x)dx and integrate, but I cannot figure out how to obtain that. Once I do, I think we sub in y=e^{2x}sinx into the integrated equation and hit x=0 to show that the result is 0=0.

    Am I on the right track?

    oh, don't over complicate this, check the solution, that's all, you need to put it into the ODE and you'll see it verifies the equality.

    Jeeeez. Over-complicating indeed, thanks man!
