Find the directions in which the function increases and decreases most rapidly at P0. Then nd the derivatives of the function in these directions. f(x.y)=x2+xy+y2. Po(2.3) V113 T 8 The direction in which the given function f(x,y) =x2 +xy + y2 increases most rapidly at P0(2,3) is u = i + [ - ]j. (Type exact answers, using radicals as needed.) 7 8 The direction in which the given function f(x,y) =x2 +xy + y2 decreases most rapidly at P0(2,3) is - u = i+ [ ]j. mm (Type exact answers, using radicals as needed.) The derivative of the given function f(x,y) =x2 + xy + y2 in the direction in which the function increases most rapidly at P0(2,3) is (Duf) (2,3) = E.
