Compute the starting and ending positions (at times $t = 0$ and $t = 1$, respectively) for the path of motion described by the following vector-valued function. Function: $\vec h(t)=\left({\cos\!\left(t\right)},{\frac{2t-4}{2t+5}},{\sin\!\left(t\right)}\right)$ Starting point: (,,) Ending point: (,,) Now compute the derivative of that same vector-valued function. Answer: $\langle$,,$\rangle$ Now compute the starting and ending velocities for that same vector-valued function. Starting velocity: $\langle$,,$\rangle$ Ending velocity: $\langle$,,$\rangle$
