Derivative of a Square Root | eMathZone
www.emathzone.com › derivative-of-square-rootFinding a derivative of the square roots of a function can be done by using derivative by definition or the first principle method. Consider a function of the form y = x . First we take the increment or small change in the function. y + Δ y = x + Δ x ⇒ Δ y = x + Δ x – y Putting the value of function y = x in the above equation, we get
