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

\int_{2 x + 3}^{x^{3}} e^{- t^{2}} d t

\frac{π}{2} erf (x^{3}) - \frac{π}{2} erf (2 x + 3)

Solution steps

\int_{2 x + 3}^{x^{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)]_{2 x + 3}^{x^{3}}

Compute the boundaries:

\frac{π}{2} erf (x^{3}) - \frac{π}{2} erf (2 x + 3)

= \frac{π}{2} erf (x^{3}) - \frac{π}{2} erf (2 x + 3)
