[?] Plot a scalar Graph with cylindrical coordinates?

[contreraspablo197 (Pablo Huerta)]

Hi,
I have a scalar Function with two variables F[r,t] in cylindrical coordinates, how can I plot it?

Hi Pablo,

What kind of plot? Something like this?

f[r_, t_] := r^2  + Sin[t]
ParametricPlot3D[{r Cos[t], r Sin[t], f[r, t]}, {r, 0, 1}, {t, 0, 2 Pi},
 ColorFunction -> "Rainbow",
 ViewPoint -> {-Pi/4, -Pi/2, -Pi/6},
 Boxed -> False,
 Axes -> False]
