Area polar curves intersecting: Find the area inside the polar curve r^2 = 2cos(17phi), and outside the polar curve r = 1.

I have been stuck at this problem for a while now, and was wondering what im doing wrong.

Find the area inside the polar curve r^2 = 2cos(17phi), and outside the polar curve r = 1.
This is what I have tried (not including my 10 past attempts):
I have also tried solving the same but including -1 in the integral

That's good. You might want to briefly state what you had to change, to help others who might read this.

Also, note that the letter you are calling "phi" is really "theta". Phi is [imath]\phi[/imath]; theta is [imath]\theta[/imath].
