Intersection of a line and an ellipse
Posted:

Hello, I am trying to solve a geometry problem but cannot seem to come up with the correct formula.
I have a line defined by two points, p1 and p2.
I also have an ellipse defined by a center point c and a radius in the xdimension a and a radius in the ydimension b. The ellipse is aligned with the coordinate axes.
I would like to know the point (if any) where the line intersects the ellipse.
Can someone give me the formula?
