Its been a little while since I've done these ones and I'm having a little trouble wrapping my head around this one.

Question:

Find the equation of the plane perpendicular to the line tangent to r(t)=(3sint)i - (2cost)j + (t)k at t=pi/2.

Would the normal vector to the plane simply be the above vector? But then would I use (0,0,0) as a point in the plane?
