WebEllipsoid modeling is essential in a variety of fields, ranging from astronomy to medicine. Many response surfaces can be approximated by a hemi-ellipsoid, allowing estimation of shape, magnitude, and orientation via orthogonal vectors. WebWe know that the volume of the solid generated by rotating the curve y = f ( x) about the x-axis is given as follows. V = ∫ x 1 x 2 π y 2 d x. Hence, the volume of the solid generated by rotating the ellipse x 2 a 2 + y 2 b 2 = 1 about the x-axis is obtained by setting y 2 = b 2 a 2 ( a 2 − x 2) in the above formula & applying the proper ...
