Consider the surface in three dimensions parameterized by u and v as follows: x(u, v) = (4 + 9 cos v) cos u y(u, v) = (4 + 9 cos 1) sin u -(, 1) = 3 sin Both of the parameters u and v take on all values from 0 to 27. Produce a graph of this surface in Matlab, with both u and v discretized with 40 points each.
