integral from 0 to 3 of e^{-t^2}

\int_{0}^{3} e^{- t^{2}} d t

0.88620 \dots

Solution steps

\int_{0}^{3} e^{- t^{2}} d t

Use the nonelementary integral:

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

= [\frac{π}{2} erf (t)]_{0}^{3}

Compute the boundaries:

0.88620 \dots

= 0.88620 \dots

\int_{- 1}^{1} - x + 1 d x

\int_{0}^{π} (sec (x))^{2} d x

\int_{0}^{15} \frac{x}{( 1 + x ) ^{\frac{3}{4}}} d x

\int_{- 8}^{1} - x^{2} - 3 x d x

\int_{0}^{3} t e^{- 0.5 t} d t
