Integration for communications systems question

[Kayne]

Hi All,

Please find the question in the attachment.

I would like to know if the intergration I have done is correct. If the intergration is correct I am not sure how to approach the rest of the question.

If someone can point me in the right direction to solves this I would appricate the help.

Thanks

In the 2nd line you have written all three 'w' symbols with the subscript '0', and only two should be (this is just a written error, your math is fine).

In the 3rd line, when you integrate e^(k*x) you should get 1/k * e^(k*x), and if you were to differentiate the result with respect to x you would get k * 1/k * e^(k*x) = e^(k*x), thus proving the initial result is correct.

It looks like you have integrated e^(k*x) and gotten 1/(k*x) * e^(k*x) in both cases.

I have had another look taking into concideration what you have said and the answer is in the attachment. Hopefully someone can let e know if I have done this correctly

Cheers
