integral from x to x^2 of (e^{t^2})

\int_{x}^{x^{2}} (e^{t^{2}}) d t

\frac{π}{2} erfi (x^{2}) - \frac{π}{2} erfi (x)

Solution steps

\int_{x}^{x^{2}} e^{t^{2}} d t

Use the nonelementary integral:

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

= [\frac{π}{2} erfi (t)]_{x}^{x^{2}}

Compute the boundaries:

\frac{π}{2} erfi (x^{2}) - \frac{π}{2} erfi (x)

= \frac{π}{2} erfi (x^{2}) - \frac{π}{2} erfi (x)

\int_{- 7}^{7} e d x

\int_{0}^{1} e^{r^{2}} r d r

\int_{1}^{\infty} \frac{1}{x ^{n}} d x

\int_{0}^{4} x^{2} - 2 x - 3 d x

\int_{0}^{\frac{1}{2}} x sin (πk x) d x
