integral from 0 to 1 of x/(1+x^4)

\int_{0}^{1} \frac{x}{1 + x ^{4}} d x

\frac{π}{8}

Decimal

0.39269 \dots

Solution steps

\int_{0}^{1} \frac{x}{1 + x ^{4}} d x

Compute the indefinite integral:

\int \frac{x}{1 + x ^{4}} d x = \frac{1}{2} arctan (x^{2}) + C

Compute the boundaries:

\int_{0}^{1} \frac{x}{1 + x ^{4}} d x = \frac{π}{8} - 0

= \frac{π}{8} - 0

Simplify

= \frac{π}{8}
