P(3,2,-1) and Q(2,-1,4), then answer the following:
(1) Find the work done in moving an object along a straight line from the point P to Q in a force
field given by F.
(2) If the force F is applied at the point P then find the Torque of F about the pointQ.
b\ The equation of a curve is y = cotx - 8 cos x, 0 < x < π, find the coordinates of the points
on the curve where dy
= 0.
