## Homework Statement

r(t) = <cos(t), t, 2sin(t)>

Find parametric equations for the circle of curvature at (0, pi/2, 2)

## The Attempt at a Solution

I know the circle of curvature is the intersection of a sphere with a plane.

Hint the professor gave me:

To get the parametric equations, look at the projections of the sphere in each of coordinate planes.

I don't know how I should approach this problem.

Any help to get me going would be much appreciated.

Thank you :)
