Thread: Area between two functions

Hi, I'm not sure if this goes under General or the Programming area, I apologize in advance if I posted this in the wrong area!

I am trying to find the area of intersection between a circle and an ellipse and I was wondering if there was a way to do it in Excel, such as integration.

I have the equation for both the circle and the ellipse, which look something like this:

Circle x^2 + y^2 = 1

Ellipse Ax^2 + B(y-C)^2 = 1

I have the coefficients A and B, and I have the vertical shift of the Ellipse (C).

Thanks in advance, any help would be appreciated!
