5. The electric potential is V volts at any point (x, y) in the æry plane and V = e-2" cos(2y). Distance is measured in feet. (a) Find the rate of change of the potential at the point (0, ") in the direction of the unit vector cos T î + sin 7 ĵ. (b) Find the direction and magnitude of the greatest rate of change of V at (0, r).
