Let the surface S in R parametrized by
f : R? → R°,
f(u, v) = (v, 2uv, (u – 1)²)
Find all (u, v) E R² at which f is not regular. - For answer entry, if you found that f is not regular at
(4, 5), (6, 3), (1, 2), enter [4,5].[6,3].[1,2] (without spaces)
f is not regular at
Find a point normal equation (E) for the tangent plane to S at f(-9,–3); use variables x, y, z.
