Hi
I am trying to find the area inside the lemniscate
r^2 = 2a^2 cos(2theta) a>0
I am having trouble graphing this in the calculator. I am in the polar mode. The a^2 is giving me problem. I am using TI 83 plus. Also i need the interval, for the above function. Please help, thank you. Once i have the interval i can find the area using
Surface Area = Integral (lower interval, upper interval) r^2 d(theta)
