Derivative of sin(9x)

Answer

9⋅cos(9⋅x)9 \cdot \mathrm{cos}\left(9 \cdot x\right)
9*cos(9*x)

Derivative of sin(9x)

Rule Used
Chain Rule
Steps
  1. Identify a composite function in sin⁡(9⋅x)\sin(9 \cdot x): 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: 9⋅c9 \cdot cos(9⋅x9 \cdot x)

The derivative of sin(9*x) is 9*cos(9*x).
