Best ResponseYou've already chosen the best response.0ultimately, you make a table with t values in one column and r(t) vectors in the other column and then plot, point for point. I was seeing a wobbly circle... but with more points, I wouldn't be surprised if it is an ellipse.

Best ResponseYou've already chosen the best response.0I guess the sin and cos give a circle in the usual way (in x and z) so then what does the additional cos in y do? If it was just t instead of cos t then that would produce a helix as t varied, whereas cos t is going to oscillate...
