Step 1

For a given curve r(t), the tangential component a_{T} and the normal component a_{N} are given by expressions shown on the white board. We therefore need to find:

- r'(t) and |r'(t)|
- r''(t)
- r'(t).r"(t)
- r'(t) x r''(t)
- |r'(t) x r''(t)|

Step 2

Please see the white board for some of the intermediate calculations.

Step 3

Please see white board for so...
