want to calculate major axis of an ellipse but struggling with equations!
I have a circle that is tilted 23.5 degrees so that an observer sees an ellipse.
I have the minor axis (b) of the ellipse (ie the height).
How can i use the degrees of tilt of the circle, to calculate the eccentricity of the observed ellipse. Then I can use eccentricity and minor axis to calculate the major axis (width)
I have looked at the equations on this page
Ellipse - Wikipedia, the free encyclopedia
but i really don't even know what I'm looking for
