MAS 3105 Lecture 14: LA Notes Lecture 14

Please Answer correctly

6. Find the decomposition of a(t) into its tangential and normal components at the indicated point:
a. r(t)=(3-4t)i+(t+1)j+t^2 k at t=1
b. r(t)=t i+e^(-t) j+t e^(-t) k at t=0

If someone could show each step and (if you know it) show me how to solve it using the program Mathematica (again, only if you know it, the step-by-step is more important) I would really appreciate it
