Is it harder to breathe in humidity or higher elevation? Why? Suppose f is differentiable for all points in R2 and f(1, 1) = 5. fx(x, y) = 3x^2y - 4y2 and fy(x, y) = x^3 - 8xy + 6y, find f(x, y).? Find the first partial derivatives of f(x, y) = sin(x - y) at the point (2, 2).At:fx(x,y), fy(x,y), fx(2,2), fy(2,2)
