Question: Given that the pressure of air at any point (r, y, z) is P(r, y, z) = e*v (x+ 22) 4xz2. SUTM At point

Given that the pressure of air at any point (r, y, z)

Given that the pressure of air at any point (r, y, z) is P(r, y, z) = e*v (x+ 22) 4xz2. SUTM At point (-1,0,-1), find the rate of change of the pressure P(x, y, z) in the direction of i+2j-k. Hence, determine the lowest rate of change in pressure P(x, y, z) and its direction in unit vector.
