How do I make a parametric plot?
How can I generate a parametric plot with Mathematica? For example, the following function should supposedly generate a spiral: $$\vec{p}(t) = \langle t\cos(t), t\sin(t) \rangle.$$ How can I generate this spiral and show it on AskBot?
Also, what about parametric plots in 3D? For example, the following function supposedly generates a helix: $$\vec{p}(t) = \langle t, \cos(t), \sin(t) \rangle.$$
What about other tools like Desmos or WolframAlpha?
