Derivada de cos(2x)
Answer
-2*sin(2*x)
Derivative of cos(2x)
- Rule Used
- Chain Rule
- Steps
- Identify a composite function in : use the chain rule = f'(g(x))·g'(x). The inner derivative is required because a stretch or shift of the input changes how fast the output moves.
- Differentiate the outer function, then multiply by the inner derivative.
- Final answer: -in()
La derivada de cos(2*x) es -2*sin(2*x).
