Who here is good with space curves defined using parametric equations? (curves in 3D)

1) x=t, y=t^2, z=e^(-t)

2) x=t, y=1/(1+t^2), z=t^2

3) x=e^(-t)*cos(10t), y=e^(-t)*sin(10t), z=sin(5t)

4) x=cos(t), y=sin(t), z=sin(5t)

5) x=cos(t), y=sin(t), z=ln(t)

you need to trace them........

roadjester · Answer

I just need a general outline. No clue how to trace them. Harder than it sounds.

its good

roadjester · Answer

k, I'll see what I can make of it

roadjester · Answer

but I'm leaving this open just in case

anonymous · Answer

if you want i can tell you how to trace these curves

roadjester · Answer

erm, sure @nitz
