## Help with IVP ODEs...

Maple

Hi,

I'm going nuts trying to get the commands(code) to solve the following two problems:

Problem 1 Verify that the given function is a solution of the initial value problem.

y:=x^2*(1+ln(x));       y'':=(3*x*y-4*y)/(x^2                      y(e)=2e^2        y'(e)=5e

## Separation of variables killing me!...

Maple
Hi, Separation of variables has been driving me nuts again, By applying the method of separation of variables solve: ux + uy =0 Separate the variables: fp1 := diff(u(x, y), x) = -(diff(u(x, y), y)); pdsolve(fp1, u(x, y)); u(x, y) = _F1(y - x) is this the correct solution? u(x,y):= _F1(y-x) If it is, what is the _F1? If it is not the solution can someone explain the correct solution to me? Regards malt
