a and b.

For the next problems, let M be the intersection of the surfaces x y2 = 1 and z = y2. Let P = (x0, yo, 20) be a point on M, and let C be the portion of M between the points (1, 0, O) and P. (a) To warm up, sketch the surfaces x y2 = 1 and z = yz, and sketch the curve M of intersection. (b) Find a parametrization for C, clearly indicating its domain. What are the starting and ending points associated with your parametrization? Hint: lety = t
