Question 2. Consider the parametrized surface S: F(u, v) = (u sec v, u tan v, u?) (-o < u < 00, -1/2 < v < 7/2) and the parametrized curve C: F(t) = (tan t, sinttant, sin? t) (-7/2 < t < n/2). %3D %3D (a) Verify that S is the hyperbolic paraboloid r² – y² = z and that C lies completely in S. (b) Find a nonzero vector ī perpendicular to the tangent vector to C at (1, ,) such that i is also tangent to S at (1, ). (c) What is the rate of change of the function f(r, y, z) = 2ry+z² along C at the point (1, 2,)? df In other words, what is dt |(1,41)
