Derivada de cos(7x)

Answer

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

Derivative of cos(7x)

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

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