integral of (Inx)/(x^2)

\int \frac{I n x}{x ^{2}} d x

I n ln ∣ x ∣ + C

Solution steps

\int \frac{I n x}{x ^{2}} d x

Take the constant out:

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

= I n \cdot \int \frac{x}{x ^{2}} d x

Cancel the common factor:

x

= I n \cdot \int \frac{1}{x} d x

Use the common integral:

\int \frac{1}{x} d x = ln (∣ x ∣)

= I n ln ∣ x ∣

Add a constant to the solution

= I n ln ∣ x ∣ + C
