Derivative of sqrt(x^2+1)

Answer

x(x2+1)12\frac{x}{\left(x^{2}+1\right)^{\frac{1}{2}}}
(1+x^2)^(-1/2)*x

Derivative of sqrt(x^2+1)

Rule Used
Chain Rule
Steps
  1. Identify a composite function in x2+1\sqrt{x^2+1}: use the chain rule ddxf(g(x))\frac{d}{dx} f(g(x)) = f'(g(x))·g'(x). The inner derivative is required because a stretch or shift of the input changes how fast the output moves.
  2. Differentiate the outer function, then multiply by the inner derivative.
  3. Final answer: (1+x2x^2)^(-1/2)*x

The derivative of sqrt(x^2+1) is (1+x^2)^(-1/2)*x.
