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??

im lookin athe parametrics and i see no sqs... how could u know its sqs and not like x^3 or something??
