Suppose a lady bug is flying about 3-space and now is
at the point (0,2,3). Say the temperature at each point is given by
T(x,y,z) = x^3 + z^2 - 2ye^x.
a) What direction should the lady bug fly in order to lower her temperature the fastest?
b) What direction could the lady bug fly in order to keep her temperature constant?
