integral from-pi to pi of xsin(x)

\int_{- π}^{π} x sin (x) d x

2 π

Decimal Notation

6.28318 \dots

Solution steps

\int_{- π}^{π} x sin (x) d x

Apply Integration By Parts

: [- x cos (x) - \int - cos (x) d x]_{- π}^{π}

= [- x cos (x) - \int - cos (x) d x]_{- π}^{π}

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

= [- x cos (x) - (- sin (x))]_{- π}^{π}

Simplify

= [- x cos (x) + sin (x)]_{- π}^{π}

Compute the boundaries:

2 π

= 2 π

3 (x^{3} - x), 0, - 1, 1

\frac{d}{d x} (5 x ln (3 x))

\frac{\partial}{\partial x} (x cos (y))

\int x^{2} cos (x^{3} + 10) d x

ln (1 - x)
