I'm trying to plot a trefoil with a parametric function in Mathematica. How would I do that? I know I can use Parametric3D to depict all of it but how do I project it on the XY, XZ, and YZ planes?
It's function is r(t)= ((1+cos(3t))cos(t),(1+cos(3t)sin(t), sin(3t)$r(t)= ((1+\cos(3t))\cos(t),(1+\cos(3t)\sin(t), \sin(3t)$.
Thank you.
