**b) Find the derivative of \(\int_{1}^{e^{x}} \ln y \, dy\).**

This question involves finding the derivative of a definite integral with a variable upper limit of integration. To solve this, you can use the Fundamental Theorem of Calculus, which states that if \( F(x) = \int_{a}^{g(x)} f(t) \, dt \), and \( f \) is continuous, then \( F'(x) = f(g(x)) \cdot g'(x) \).

Therefore, you will:

1. Identify the function \( f(y) = \ln y \).
2. Use the Fundamental Theorem of Calculus to differentiate, taking into account the chain rule for the upper limit \( e^x \).
