Z=t, which means the height increases with the variable t.

Its going to lie on a circular cylinder, but it will be in the shape of a HELIX, wrapped around that cylinder of course.

Hey thanks for the answer but how could u just take an x^2 + y^2 = cos(t)^2 + sin(t)^2 = 1 just like that??cyrusabdollahi said:
