Homework Statement
Find parametric equations for the tangent line to the curve with the given parametric equations at the specified point.
x = 6 cos t, y = 6 sin t, z = 6 cos 2t; (3√3, 3, 3)
Homework Equations
The Attempt at a Solution
So I understand that r(t)= 6cost t, 6sint, 6cos2t
and r'(t)= -6sint, 6cost, -12sin2t
So here is the questions, how do I find what the value of t is at points (3√3, 3, 3)
