Here's another problem. I'm given the vector (t, cos2t, sin2t) and I'm asked to sketch the curve with the given vector equation. Indicate with an arrow the direction in which t increase. What I do know are the parametric equations, x=t, y=cos2t, z=sin2t, but from this point know I not in...

n!kofeyn, i shall do just what you suggested and i appreciate your input for it helped me out even the more. i, again, am most appreciative for everyone's help. i am the PotnlMathmtcn.

I'm most appreciative for your help. I understand that I must have more familiarity, namely, with circles, ellipses, hyperbolas, etc. What was confusing for me is that 2 squared variables equal to 1, I thought, resulted in a circle. And although this might sound stupid, what I'm dealing with...
