Question deals with Parametrization of curves and surfaces in three dimensions - in vector calculus

3) In each item below, you are given a curve or a surface in R3. For each one, provide a arametrization, clearly indicating its domain. Sketch the object and indicate the orientation associated with your parametrization (a) The intersection between 23: + y : 2 and 2:2 + 2'2 : 1 in the rst octant. (b) The surface given by y3 : 1:2 + 22
