Transcript text: Specify $u$ and $d u$.
(Use symbolic notation and fractions where needed.)
Solution
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
\[
u = u(x)
\]
\[
du = dx \cdot \frac{d u(x)}{d x}
\]
