I have a problem I hope you guys can help me with.

It's quite simple I think, but there is one thing that I can't figure out.

2. Relevant equations

I have to use polar coordinates to evaluate this integral:

See image

3. The attempt at a solution

I really don't have an attempt, because I can't remember, and it doesn't say so in my book, how I turn the dx limits into polar coordinates (theta).

The dy limits are:

x = r*cos(theta)

y=r*sin(theta)

, where you just insert them at the x and y. But it's the dx limits that annoy me. Do I just leave them as they are (Which sound unlogical to me), or do I change them into angles ? If yes, how ?

Hope you can help.
