Thread: Finding the area of the curve

1. Finding the area of the curve

Find the area that encloses.

r = 2 + cos(2θ)

For finding the interval I put r = 0. Now I dont know how to solve for r. I am stuck.

Any help

thx

2. Integrate $\frac12r(\theta)^2$ with respect to theta over [0,2pi].

how do you get [0,2pi] ?
