Homework Statement
find the length of the cardiot r = 1+cos(Θ)
I'm going to use { as the integral sign
all integrals are definite between 0 and Pi
Homework Equations
L = 2 {sqrt[(r^2(Θ))+(dr/dΘ)^2]dΘ
The Attempt at a Solution
L=2* {sqrt[2+2cos(Θ)] dΘ
I'm having a really hard time trying to integrate sqrt[2+2cos(Θ)] dΘ and was hoping someone could explain to me how you integrate that.
Thanks.
