By about how much will g(x,y,z)=2x + x cos z-y sin 2 + y change if the point P(x,y,z) moves from Po(1-2,0) a distance of ds = 0.2 unit toward the point P(-1,0,2)? dgar (Type an integer or decimal rounded to four decimal places as needed) By about how much will g(x,y,z)=2x + x cos z-y sin 2 + y change if the point P(x,y,z) moves from Po(1-2,0) a distance of ds = 0.2 unit toward the point P(-1,0,2)? dgar (Type an integer or decimal rounded to four decimal places as needed)
