Thread: Cosine Transform Question

Hi,

I'm trying to solve:



And I've got as far as this:







However I don't understand how to algebraically solve this for the given answer:



I don't see how the right term has obtained the denominator underneath

I'm wondering if my tutor has made a mistake?

Any help would be appreciated.
Thanks in advance.

You don't make it clear what it is that you are trying to do. You say solve, but solve what I don't know, only guess. Do they not have equals signs in Kent ?
As to the bit at the end though, you should be able to see that if you multiply out the bracket you'll get the line above.

Ah.. got it now, was having a slow moment.

Many thanks.
