The Question is:

Provide equations for the velocity of the moth in all 3 directions. Note that these are actually the components of the 3D velocity vector in parametric form (ie: functions of t).

Where:

x=sin(t)

y=t+1

z=cos(t)

 

(do i make y=t+1 into t=y-1??)

Where:

x=sin(t)

y=t+1

z=cos(t)

$$\\\frac{dx}{dt}=cos(t)\\\\
\frac{dy}{dt}=1\\\\
\frac{dz}{dt}=-sin(t)\\\\$$

I think this is right.  t is time.
