    Find the Exact length of the Polar Curve

    Homework Statement 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. Homework Equations L= ∫√(r^2+(dr/dθ)^2)dθ The Attempt at a Solution r=2(1+cosθ) dr/dθ=-2sinθ L=∫√((2+2cosθ)^2+(-2sinθ)^2)dθ...
