integral of-1/(2/x y)

\int - \frac{1}{\frac{2}{x} y} d y

- \frac{x}{2} ln ∣ y ∣ + C

Solution steps

\int - \frac{1}{\frac{2}{x} y} d y

Take the constant out:

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

= - \frac{1}{\frac{2}{x}} \cdot \int \frac{1}{y} d y

Simplify

= - \frac{x}{2} \cdot \int \frac{1}{y} d y

Use the common integral:

\int \frac{1}{y} d y = ln (∣ y ∣)

= - \frac{x}{2} ln ∣ y ∣

Add a constant to the solution

= - \frac{x}{2} ln ∣ y ∣ + C
