Suppose that, at a specific point p, the directional derivatives of the function f (x, y ) are known in two nonparallel directions given by the unit vectors u and v. in particular, suppose that d f d s = a in the u direction and d f d s = b in the v direction. is it possible to find the gradient of f at the point p? if so, show how to do it. if not, explain why not.

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
