Derivative of cos(x^7)

Answer

−7⋅sin(x7)⋅x6-7 \cdot \mathrm{sin}\left(x^{7}\right) \cdot x^{6}
-7*sin(x^7)*x^6

Derivative of cos(x^7)

Rule Used
Chain Rule
Steps
  1. Identify a composite function in cos⁡(x7)\cos(x^7): 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: -7⋅s7 \cdot sin(x7x^7)*x6x^6

The derivative of cos(x^7) is -7*sin(x^7)*x^6.
