integral of pi/x

\int \frac{π}{x} d x

π ln ∣ x ∣ + C

Solution steps

\int \frac{π}{x} d x

Take the constant out:

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

= π \cdot \int \frac{1}{x} d x

Use the common integral:

\int \frac{1}{x} d x = ln (∣ x ∣)

= π ln ∣ x ∣

Add a constant to the solution

= π ln ∣ x ∣ + C

\int sec (9 x) tan (9 x) d x

\int (1 - y^{2})^{\frac{1}{2}} d y

\int \frac{5 - x}{x ^{3}} d x

\int \frac{1}{8 - 12 x - x ^{2}} d x

\int (x + 3)^{2} e^{x} d x
