QUESTION:
47 48 Find the vectors , , and at the given point.rt cos t, sin t, ln cos t 1, 0, 0x 2
ANSWER:Step 1 of 3
It is known that is tangent, so the formula is given by:
It is given that so differentiate w. r. t. to get:
The magnitude of the vector is given by:
The tangent is at point , hence , so it follows:
Hence the value of the tangent vector is .
