For spherical coordinates: use coordinates such as (2; 30°; 40°).

For parametric equations: use the commands Curve( ) and/or Surface( ). The input suggestions are clear. You have to provide the parametric aexpressions for x, y and/or z and define the parameter in it and the borders of the used parameter(s).

If you want specific information for a specific equation, please specify your question.

The command Surface(2cos(t), l, 2sin(t), t, 0°, 180°, l, -2, 2) creates a half lying cylinder while the command Curve(5 cos(t), 2 sin(t), t, 0°, 270°) creates 3/4 of an ellips.
