Hi,

I am currently trying to find the area of segment of an elipse, I know the area of the segment for the circle related to the elleipse. So all i need to do is times the area of the circle segment by (b/a).

The problem I have is that I don't know b. Am i right in thinking that if I know some points on the ellipse that I can rearange the forumal of ellipse to this:

Sorry its all so long winded
