integral from-1 to 0 of xarcsin(x)

\int_{- 1}^{0} x arcsin (x) d x

\frac{π}{8}

Decimal Notation

0.39269 \dots

Solution steps

\int_{- 1}^{0} x arcsin (x) d x

Apply Integration By Parts

: [\frac{1}{2} x^{2} arcsin (x) - \int \frac{x ^{2}}{2 1 - x ^{2}} d x]_{- 1}^{0}

= [\frac{1}{2} x^{2} arcsin (x) - \int \frac{x ^{2}}{2 1 - x ^{2}} d x]_{- 1}^{0}

\int \frac{x ^{2}}{2 1 - x ^{2}} d x = \frac{1}{4} (arcsin (x) - \frac{1}{2} sin (2 arcsin (x)))

= [\frac{1}{2} x^{2} arcsin (x) - \frac{1}{4} (arcsin (x) - \frac{1}{2} sin (2 arcsin (x)))]_{- 1}^{0}

Compute the boundaries:
