Homework Statement
Find the vectors T, N, and B at the given point.
r(t) = (sin(t), cos(t), ln(cos(t))), P = (0,1,0)
Homework Equations
T(t) = r'(t) / | r'(t) |
N(t) = T'(t) / | T'(t) |
B(t) = T(t) x N(t)
The Attempt at a Solution
I am stuck on how to solve for t. I am not sure how you would calculate for the parameter t in this equation.
