10.5 - Parametrized Surfaces
1. Describe the surface with the parametrization x(u, v) = cos(u), y(u, v) = sin(u), z(u, v) = v
for 0 <us2n and v E R.
(Suggestions: Simply Googling "graph parametric surfaces" will bring you to a Desmos page
where you can graph this surface using technology. It may also help to observe that x and y
have "circle-ish" equations, while z has a "line-ish' equation, and although x and y are related, z
is not related to either x or y.)
