1. (8 pts) Find a parameterization of the part of the surface z = er* that lies inside the cylinder x* + y =4. 2. (a) (20 pts) Find an equation for (a) the normal line and (b) the tangent plane for the surface given by r(u, v) = (3u +2v, 5u , v ) at the point P(7,5,4). Hint: Find (up, v. ) where r(up, v. ) = (7, 5,4)
