The temperature T at (x,y,z) in the 3D space is given by T(x,y,z) = ln(1+x2y2+z2).
a) Find rate of change of T at the point P(1,-1,-1) in the direction of Q(2,0,0)?
b) In which direction from P(1,-1,-1) does the temperature T increase most rapidly?
c) What is the maximum rate of change of T at P(1,-1,-1)?
