Question) The polar curve C is given by the polar equation r=1+cos(theta)
Find the length of C.
Answer) This is what I have so far:
r = 1 + cos(theta)
Since L = INT(sqrt[1 + (dr/d(theta))^2])d(theta)
L = int(sqrt[1+sin^2(theta)])d(theta) (with integral from 0 to 2)
then Im stuck... please help to solve this!!
