Derivada de sin(9x)+cos(2x)
Answer
-2*sin(2*x)+9*cos(9*x)
Derivative of sin(9x)+cos(2x)
- Rule Used
- Sum Rule
- Steps
- Differentiate + term by term. The sum rule says the derivative of a sum is the sum of the derivatives, and the derivative of a constant term is 0, so that term disappears.
- Final answer: -in()+os()
A derivada de sin(9*x)+cos(2*x) é -2*sin(2*x)+9*cos(9*x).
