Derivative of acos(x/3)

Answer

−13⋅−x29+1-\frac{1}{3 \cdot \sqrt{-\frac{x^{2}}{9}+1}}
(-1/3)*sqrt((-1/9)*x^2+1)^(-1)

Derivative of acos(x/3)

Rule Used
Chain Rule
Steps
  1. Identify a composite function in arccos⁡(x/3)\arccos(x/3): 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: (-1/3)*((−1/9)⋅x2+1)−1\sqrt((-1/9) \cdot x^2+1)^{-1}

The derivative of acos(x/3) is (-1/3)*sqrt((-1/9)*x^2+1)^(-1).
