Given f(x, y, z)=√4x² + 3y² + 2z², find fz(x, y, z) = 2 fy(x, y, z) = fz(x, y, z)=

f(x, y) = √5x² + 3y² fz(5,-2) =

(b) Show that the function defined by xy √x²+y² f(x, y) 0 if (x, y) = (0,0) is not differentiable at point (0,0). 20 if (x, y) = (0,0),

Find fy(x,y) if f(x,y) = 7x2 +5y2 -6. fxy (x.y) =

Given f(x, y) = 6x² + 1x²y¹ + 6y5, find fz(x, y) = fy(x, y) = fxz(x, y) = fxy(x, y) = −

Given f(x, y) = 3x6 - 6x²y² + y³, find fx(x, y) = == fy(x, y) = fxx(x, y) = fxy(x, y) =

Given f(x, y) = 6x¹ - 1x²y6 + 2y5, find fz(x, y) = fy(x, y) = fax (x, y) = fay(x, y) =
