I know that the unit vector function is equal to:
If . . . . Why aren't these reduced?
We have: .
. . . . . .
I know that the unit vector function is equal to T'(t) / |T'(t)|
If T(t) is < , , >
To find T'(t), would I simply take the derivative of each element using the quotient rule? I did this on paper, and was getting results that were different than the answers in the back of my book. Any ideas? Thanks
Edit: what on earth is wrong with my latex
