Derivative of cos(x^2+3)

Answer

−2⋅sin(x2+3)⋅x-2 \cdot \mathrm{sin}\left(x^{2}+3\right) \cdot x
-2*sin(3+x^2)*x

Derivative of cos(x^2+3)

Rule Used
Chain Rule
Steps
  1. Identify a composite function in cos⁡(x2+3)\cos(x^2+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: -2⋅s2 \cdot sin(3+x2x^2)*x

The derivative of cos(x^2+3) is -2*sin(3+x^2)*x.
