To integrate ( \int \frac{1}{\sqrt{2x}} , dx ), we use the substitution ( u = \sqrt{2x} ). This implies ( du = \frac{1}{\sqrt{2x}} , dx ). Substituting these into the integral gives:

( \int \frac{1}{\sqrt{2x}} , dx = \int du = u + C ),

where ( C ) is the constant of integration. Finally, substituting back ( u = \sqrt{2x} ) gives the result:

( \int \frac{1}{\sqrt{2x}} , dx = \sqrt{2x} + C ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
