Re: Separation of Variables

Hmm...

You can't do that w substitution as you will get but there is no in the integral to cancel it out

Re: Separation of Variables

I would agree that you should just use the result given by jgv115 but you *can* use the substitution.

You should end up with

I see, you need to multiply by 1 before it works..:p

Re: Separation of Variables

I'm sorry. I am still not sure what substitution to use. How would I end up with my substitution as 1/w^{2 }??

You had
