integral of 1/pi xsin(x)

\int \frac{1}{π} x sin (x) d x

\frac{1}{π} (- x cos (x) + sin (x)) + C

Solution steps

\int \frac{1}{π} x sin (x) d x

Take the constant out:

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

= \frac{1}{π} \cdot \int x sin (x) d x

Apply Integration By Parts

= \frac{1}{π} (- x cos (x) - \int - cos (x) d x)

\int - cos (x) d x = - sin (x)

= \frac{1}{π} (- x cos (x) - (- sin (x)))

Simplify

= \frac{1}{π} (- x cos (x) + sin (x))

Add a constant to the solution

= \frac{1}{π} (- x cos (x) + sin (x)) + C
