Graph the parametric equations:
x=cos(t) y=sin(t) z=cos(2t)

How would I go about solving this problem? thanks!

  • Calculus -

    well, you know that the x-y part is just a circle. So, as x-y moves around the circle, z bobs up and down twice. It's saddle-shaped.

    plot x=cos(t), y=sin(t), z=cos(t)
