Question

33-36 is one question as in the book

But i want only 33

sin θ + r cos(θ/2) z = r sin(θ/2) where _ 흘 バ2 and 0 2m is called a M bius θ strip. Graph this surface with several viewpoints. What is unusual about it? 33-36 Find an equation of the tangent plane to the given parametric surface at the specified point. 33. x = u+u, y= 3112, z = u-u; (2,3,0) 34. x 112 + 1, y = u3 + 1, z u + u; (5,2,3) 35. r(u, u) = u cos u 1 + 11 sin u J + u k; u = 1, u = T/3 36. r (u, o) sin u i + cos u sin uj + sin uk;
