# Chapter 2 - Differentiation - 2.2 Exercises: 22

The derivative is $cos(x)$.

#### Work Step by Step

The function is a sum of two functions, hence the overall derivative is the sum of the derivative of $7$ + the derivative of sin(x). The derivative of $7$ is $0$ and the derivative of $sin(x)$ is $cos(x)$; hence, the overall derivative is $cos(x)$.
