\int \frac{1}{\sqrt{2 x}} d x

Solution
Solution Steps
To solve the integral \(\int \frac{1}{\sqrt{2x}} \, dx\), we can use a substitution method. Let \(u = 2x\), then \(du = 2dx\). This substitution simplifies the integral into a more manageable form.
Step 1: Substitution
To solve the integral \(\int \frac{1}{\sqrt{2x}} \, dx\), we use the substitution \(u = 2x\). Then, \(du = 2dx\) or \(dx = \frac{du}{2}\).
Step 2: Simplify the Integral
Substitute \(u\) and \(dx\) into the integral:
\[
\int \frac{1}{\sqrt{2x}} \, dx = \int \frac{1}{\sqrt{u}} \cdot \frac{du}{2} = \frac{1}{2} \int \frac{1}{\sqrt{u}} \, du
\]
Step 3: Integrate
The integral \(\int \frac{1}{\sqrt{u}} \, du\) is a standard integral:
\[
\int \frac{1}{\sqrt{u}} \, du = 2\sqrt{u}
\]
Thus,
\[
\frac{1}{2} \int \frac{1}{\sqrt{u}} \, du = \frac{1}{2} \cdot 2\sqrt{u} = \sqrt{u}
\]
Step 4: Substitute Back
Replace \(u\) with \(2x\):
\[
\sqrt{u} = \sqrt{2x}
\]
