Question: For the given position vectorsr(t), compute the velocityr(t)for the given value oft. A)Letr(t)=cos4t,sin4t Thenr(/4)=, B)Letr(t)=t2,t3 Thenr(5) r(5)=, C)Letr(t)=e^4ti+e^5tj+tk Thenr(5)=i+ j+k

For the given position vectorsr(t), compute the velocityr(t)for the given value oft.

A)Letr(t)=cos4t,sin4t

Thenr(/4)=,

B)Letr(t)=t2,t3

Thenr(5)

r(5)=,

C)Letr(t)=e^4ti+e^5tj+tk

Thenr(5)=i+ j+k
