Find the unit tangent vector to the curve defined by
7(t) = (4 cos(t), 4sin(t), 2 sin (t))
at t = T.
T(T) =
Use the unit tangent vector to write the parametric equations of a tangent line to the curve at
t = T.
æ(t):
y(t)
z(t)
Note from Sam: To get the system to accept your answer, you need to use the parametrization
T(a) · t + 7(a), NOT the parametrization T (a) · (t – a) + 7(a).
