## Homework Statement

Eliminate the parameters u and v to obtain a Cartesian equation, thus showing that the given vector equation represents a portion of the surface named. Also, compute the fundamental vector product dr/du x dr/dv in terms of u and v.

## Homework Equations

Ellipsoidr(u,v) =

*a*sinucosv

**i**+

*b*sinusinv

**j**+

*c*cosu

**k**

## The Attempt at a Solution

I can find the cross product easy enough(*abc*, but how should I go about getting rid of the parameters?

*sinu((sinucosv/**a**)***i****+(sinusinv/***b**)***j****+(cosu/***c**)***k****)**
