Solution Steps

To specify \( u \) and \( du \), we need to define a function \( u \) and then find its differential \( du \). The differential \( du \) is given by the derivative of \( u \) with respect to \( x \) multiplied by \( dx \).

Step 1: Define the Variable

We start by defining the variable \( x \).

Step 2: Define the Function \( u \)

Next, we define the function \( u \) as \( u(x) \).

Step 3: Calculate the Differential \( du \)

To find the differential \( du \), we take the derivative of \( u(x) \) with respect to \( x \) and multiply it by \( dx \): \[ du = \frac{d u(x)}{d x} \cdot dx \]

Final Answer

\[ u = u(x) \] \[ du = dx \cdot \frac{d u(x)}{d x} \]
