Here are some examples of plotting curves in space. with(plots): spacecurve([cos(t),sin(t),t], t=0..4*Pi, axes=normal, color=blue); spacecurve([cos(t),sin(t),cos(2*t)], t=0..4*Pi,axes=normal, color=blue); spacecurve([cos(t),sin(t),cos(4*t)], t=0..4*Pi,axes=normal, numpoints=1000, color=red); spacecurve([cos(t),sin(t),abs(2*cos(3*t)+1)], t=0..2*Pi, axes=normal);
