1) Calculate the derivatives of following functions with respect to x. (i) (ii) (iii) (iv) y = f (x) = x + (1+x) y = (x + 2) + (1 + x) 3 y = (x + 2) (3x + x 0.2) y = (x0.5 + 5)+(2x + 1) 0.5 2) Calculate the partial derivatives of following functions with respect to X and with respect to X2. (i) y = f(x1,x2) = 3x + 5x2 (ii) y = (x1, x2) = x + (2x + 1) + 4x.x + x.x. (iii) y = f(x1,x2) = x0.75x2. 0.25 (iv) y = f (x1, x2) = (x0.5x2.5) 2 (v) y = f (x1,x2) = 4x0.5 + x2 (vi) y = f(x1,x2) = xx2 + x + x
