integral of 1/(2u)

\int \frac{1}{2 u} d u

\frac{1}{2} ln ∣ u ∣ + C

Solution steps

\int \frac{1}{2 u} d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= \frac{1}{2} \cdot \int \frac{1}{u} d u

Use the common integral:

\int \frac{1}{u} d u = ln (∣ u ∣)

= \frac{1}{2} ln ∣ u ∣

Add a constant to the solution

= \frac{1}{2} ln ∣ u ∣ + C
