integral of e^{(x-1)^2}

\int e^{(x - 1)^{2}} d x

\frac{π}{2} erfi (x - 1) + C

Solution steps

\int e^{(x - 1)^{2}} d x

Apply u-substitution

= \int e^{u^{2}} d u

Use the nonelementary integral:

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

= \frac{π}{2} erfi (u)

Substitute back

u = x - 1

= \frac{π}{2} erfi (x - 1)

Add a constant to the solution

= \frac{π}{2} erfi (x - 1) + C
