Final answer:
The derivative of both functions is equal.
Step-by-step explanation:
To find the derivative of the given functions, we can use the chain rule and the power rule. Let's start with function a. The derivative of (x - 2)^2 is 2(x - 2), and the derivative of (sin(x) + 1)^2 is 2(sin(x) + 1)cos(x). Now, let's find the derivative of function b. It follows the same steps as function a. The derivative of (x - 2)^2 is 2(x - 2), and the derivative of (sin(x) + 1)^2 is 2(sin(x) + 1)cos(x). Therefore, the derivatives of both functions are equal.
