# Math Help - Help with area of region

1. ## Help with area of region

Find the area of the region bounded by the x-axis and the cardiod r=1+cos(theta) from 0 to pi.

Can anyone give me some tips on how to approach this problem?
Thanks in advance.

2. That's just the area of a region in polar coordinates right?

$A=1/2\int_{\theta_1}^{\theta_2} \left[f(\theta)\right]^2 d\theta$

Tips you say? The best I can think is to find this section in your calculus book, work through the one or two examples they'll have, then work through yours.
