# Math Help - Integration

1. ## Integration

Hi, I would really appreciate it if someone can help with this:

Let A denote the value of the integral

integral_0^(pi) cos(x)/ (x+2)^2 dx (From 0 to pi)

Compute the following integral in terms of A:

integral_0^(pi/2) (sinx cosx)/ (x+1) dx.

Thank you.

Are you sure you have a square in the denominator in first integral?

Maybe you really mean:

integral_0^(pi) cos(x)/(x+2) dx

If so, I have a way to do it.

3. Hi, sorry for the long delay.

Yes, as a matter of fact, the square is not supposed to be there. If u still have a way to do it, I will like to see it.

Can you check the problem again.
Is there a cosine in the first one.
Is the denominator (x+2) or (x+1)?

I remember I did it, but I threw the paper away. I am beginning to think that I did a different problem.
