40) Find an equation of the tangent plane to the parametric surface at the given point. If you have software that graphs parametric surfaces, use a computer to graph the surface and the tangent plane. x = u^2, y = v^2, z = uv; u = 1, v = 1

39-43 Find an equation of the tangent plane to the parametric sur-
face at the given point. If you have software that graphs parametric
surfaces, use a computer to graph the surface and the tangent plane.
39. x = u + v, y = 3u², z = u v;
—

40.x=u², y=v², z = uv; u = 1, v = 1
41. r(u, v) = u² i + 2u sin v j + u cos vk; u = 1, v = 0
42. r(u, v)
=
uvi + u sin vj + v cos u k; u = 0, v = π
43. r(u, v) = ui + ln(uv) j + vk; u = 1, v = 1
