ParametricPlot3D question
11/04/05 01:00am

Could you please help me to understand better the ParametricPlot3D function.
I found an example:
ParametricPlot3D[{Sin[t], Cos[t], u}, {t, 0, 2Pi}, {u, 0, 4}] - it produces the cylinder.
I understand that the "u" parameter is actually the height of the created cylinder.
Could you help me to understand what are Sin[t] and Cos[t] and that the t runs from 0 to 2Pi?

And the question -- if the above function creates the cylinder, then how can I specify the radius/diameter for it?

and just one more related question?
in a very similar function:
ParametricPlot3D[{Sin[t], Cos[t], t/3}, {t, 0, 15}]
What are Sin[t], Cos[t]
If the function produces the 3D curve -- How to set the length of the curve and it diameter?

Thank you very much for your support!
