Calculate r'(t) and T(t) and evaluate T(1).
r(t) = \langle 10 + 11t, t^2, 5 - t^2 \rangle
(Give your answers using component form or standard basis vectors. Express numbers in exact form. Use symbolic notation and
fractions where needed.)
r'(t) = \langle 11, 2t, -2t \rangle
T(t) = \frac{\langle 11, 2t, -2t \rangle}{\sqrt{121 + 8t}}
Incorrect
T(1) = \left\langle \frac{11}{\sqrt{129}}, \frac{2}{\sqrt{129}}, -\frac{2}{\sqrt{129}} \right\rangle
