The temperature at a point (x,y,z) is given by T(x, y, z) = ,where T is measured in degrees Celsius and x,y, and z in meters There are lots of places to make silly errors in this problem: just try to keep track of what needs to be a unit vector Find the rate of change of the temperature at the point (-1,1,-2) in the direction toward the point (-4,-1,-2). In which direction (unit vector) does the temperature increase the fastest at (-1,1,-2)? ( ) What is the maximum rate of increase of T at(-1,1,-2)?
