The temperature at the point (x, y, z) in space is given by T ( x, y, z) = x + yz. A fly is at the point (1, 2, 1). In what direction should he begin to fly to cool off as quickly as possible. Your answer should be a unit vector in the requested direction.

Step-by-step explanation:

From the question we are told that

Temperature is given \

A fly is at (1,2,1)

Generally the direction of fly is given by

Mathematically solving for the vector direction

Therefore this the direction which should be taken to cool down soonest

i dont know sorry
