Comment/Request

I need to compute the lateral surface and volume of an elliptic frustum, BUT the base and top ellipses DO NOT have the same eccentricity,i.e., if ellipse semi major and minor axes for the base and top are a1,b1, and, a2, b2; b2/a2 is not equal to b1/a1 as one of your calculators assume. They are completely free 2 ellipses with H the distance between the centers. *THANK YOU SO VERY MUCH!*
