# Plot a parametric equation in cylindrical coordinates

I'm looking for a way to plot this parametric equation on cylindrical coordinates.

r = e^t
theta = t+1
z = e^2t


Any help would be appreciated

• Well, % /. "Spherical"->"Cylindrical".

I created this function to convert from cylindrical to cartesian:

thing[r_, theta_, z_] := {r Cos[theta], r Sin[theta], z}


Then use ParametricPlot3D

ParametricPlot3D[thing[Exp[t], t + 1, Exp[2 t]], {t, 0, 1}] • your answer was what i was looking for, I have no problem plotting parametric equations on spherical coordinates but somehow this eluded me. Thanks you very much Apr 2 '15 at 23:08
