Derivative of cos(x^9)
Answer
-9*sin(x^9)*x^8
Derivative of cos(x^9)
- 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()*
The derivative of cos(x^9) is -9*sin(x^9)*x^8.
