Derivada de cos(x^8)

Answer

−8⋅sin(x8)⋅x7-8 \cdot \mathrm{sin}\left(x^{8}\right) \cdot x^{7}
-8*sin(x^8)*x^7

Derivative of cos(x^8)

Rule Used
Chain Rule
Steps
  1. Identify a composite function in cos⁡(x8)\cos(x^8): 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: -8⋅s8 \cdot sin(x8x^8)*x7x^7

A derivada de cos(x^8) é -8*sin(x^8)*x^7.
