integral from 1 to 3 of e^{x^2}

\int_{1}^{3} e^{x^{2}} d x

\frac{π erfi ( 3 ) - π erfi ( 1 )}{2}

Solution steps

\int_{1}^{3} e^{x^{2}} d x

Use the nonelementary integral:

\int e^{x^{2}} d x = \frac{π}{2} erfi (x)

= [\frac{π}{2} erfi (x)]_{1}^{3}

Compute the boundaries:

\frac{π erfi ( 3 ) - π erfi ( 1 )}{2}

= \frac{π erfi ( 3 ) - π erfi ( 1 )}{2}

\int_{1}^{b} \frac{1}{( x + 1 ) ^{2}} d x

\int 2 e^{- 4 x} d x

\int \frac{1 - x}{x} d x

y = e^{6 x} cos (π x), (0, 1)

\frac{\partial}{\partial x} (- 3 x y)
