Circumference of a Cassini oval
How does one find the circumference of a Cassini oval given an equation in the form $((x-a)^2+y^2)((x+a)^2+y^2)=b^4$ ?

Hey ZeroDivisionError.

Are you familiar with arc-length in calculus?

Unfortunately, I am not. But I know what integrals, derivatives, and series are.
