Find the derivative of 1 / √ X & #

Find the derivative of 1 / √ X & #

f'(x)=-1/2x^(-3/2)

The derivative of X & # / X-1?

The derivative of X & # 178; / (x-1) is:
[x²/(x-1)]'=[(x²)'×(x-1)-x²×(x-1)']/(x-1)²
=[2x×(x-1)-x²×1]/(x-1)²
=(2x²-2x-x²)/(x-1)²
=(x²-2x)/(x-1)²

Find the derivative of (1) y = sin43xcos34x (2) y = 2 (ex / 2 + E-X / 2) (3) y = a2x + 1

(1)y'=43cos43x*cos34x-34sin43xsin34x;
(2)y'=2[(x/2)*e^(x/2)-x/2)*e^(-x/2)];
(3)y'=2x*a^2xlna
