Derivative of 4*cos(x)
Answer
-4*sin(x)
Derivative of 4*cos(x)
- Rule Used
- Constant Multiple Rule
- Steps
- os(x) is a constant times a function of x. The constant is a fixed stretch of the slope, so it factors out and the remaining function is differentiated.
- Final answer: -in(x)
The derivative of 4*cos(x) is -4*sin(x).
