integral from 0 to 1 of e^{-y^2}

\int_{0}^{1} e^{- y^{2}} d y

0.74682 \dots

Solution steps

\int_{0}^{1} e^{- y^{2}} d y

Use the nonelementary integral:

\int e^{- y^{2}} d y = \frac{π}{2} erf (y)

= [\frac{π}{2} erf (y)]_{0}^{1}

Compute the boundaries:

0.74682 \dots

= 0.74682 \dots

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

\int_{- 1}^{3} (x^{2}) d x

\int_{0}^{2} \frac{1}{25 - x ^{2}} d x

\int_{\frac{π}{5}}^{π} ∣ cos (x) ∣ d x

\int_{0}^{1} \frac{x}{x ^{2} + 2} d x
