integral from 0 to 1 of arcsin(y)

\int_{0}^{1} arcsin (y) d y

\frac{π}{2} - 1

Decimal

0.57079 \dots

Solution steps

\int_{0}^{1} arcsin (y) d y

Apply Integration By Parts

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

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

= [y arcsin (y) - (- 1 - y^{2})]_{0}^{1}

Simplify

= [y arcsin (y) + 1 - y^{2}]_{0}^{1}

Compute the boundaries:

\frac{π}{2} - 1

= \frac{π}{2} - 1
