1. The problem statement, all variables and given/known data Find the Exact length of the Polar Curve for r=2(1+cosθ) No limits of Integration were given which I found to be odd. 2. Relevant equations L= ∫√(r^2+(dr/dθ)^2)dθ 3. The attempt at a solution r=2(1+cosθ) dr/dθ=-2sinθ L=∫√((2+2cosθ)^2+(-2sinθ)^2)dθ =∫√(4cos^2θ+4sin^2θ+8cosθ+4)dθ =∫√(8cosθ+8)dθ Got to this point and figured I did something incorrectly.
