so when i get the unit tangent vector it is <sinh(t)/(sinh(t)+cosh(t)),-cosh(t)/(sinh(t)+cosh(t)),0> how do i go about taking the derivative of that in order to find the unit normal vector?
Homework Statement
r(t) = <cosh(t), -sinh(t), t>
not given a value for t.
Homework Equations
r'(t)
N(t)
The Attempt at a Solution
T = r'(t)/distance[r'(t)]
how do you find unit tangent vector and the unit normal vector without being given a value for t?
r'(t) =...
