This question has several parts that must be completed sequentially. if you skip a part of the question, you will not receive any points for the skipped part, and you will not be able to come back to the skipped part. tutorial exercise find a parametric representation for the surface. the part of the sphere x2 + y2 + z2 = 100 that lies above the cone z = x2 + y2 . step 1 by re-ordering the sphere equation, we have z2 = 100 − x2 − y2. we can then parameterize this surface in rectangular coordinates as with x = u and y = v. (enter your answer as a comma-separated list of equations. let x, y, and z be in terms of u and/or v.)
