## Solution - partial differential equation...

Maple

I'm still a maple beginner and looking for a workable solution to the following problem. I have already solved these "by hand" and would now like to control them.

The following equation should be solved:

`diff(u(x, t), t, t)-c^2*(diff(u(x, t), x, x))`

The approach function would be for example:

`u := a(x)*sin(k1*(-c*t+x))`

It would be great if maple could give me the solution again in this example:

`solution = -c^2*(d^2*a*sin(k1*(-c*t+x))/dx^2+2*d*a*k1*cos(k1*(-c*t+x))/dx)`

How exactly do I do this best?
Thanks a lot!

## Solution control of a partial differenti...

Maple

Hello,

given is the lower, partial differential equation. I have solved this (hopefully) correctly. I was given the tip to do in Maple a simple control in which the solution is inserted into the original equation. Since I'm quite inexperienced in maple, I would like to ask you for help on how I do that best!

Thanks a lot!
