An ant is crawling on a hot plate and z= T(x,y) gives the temperature on the plate in °C at position (x, y) (measured in cm). The ant's current position is (1, -2). It senses that to cool down as fast as possible it should move towards the point (-1,1) and it will cool at a rate of 2 C/cm. Give the gradient vector of T at(1, -2). Give each component numerically rounded to 2 decimal places. f(3,-2) =( Note:...
