integral from 0 to 1/2 of arcsin(x)

\int_{0}^{\frac{1}{2}} arcsin (x) d x

\frac{π}{12} + \frac{3}{2} - 1

Decimal Notation

0.12782 \dots

Solution steps

\int_{0}^{\frac{1}{2}} arcsin (x) d x

Apply Integration By Parts

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

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

\int \frac{x}{1 - x ^{2}} d x = - 1 - x^{2}

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

Simplify

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

Compute the boundaries:

\frac{π}{12} + \frac{3}{2} - 1

= \frac{π}{12} + \frac{3}{2} - 1

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