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

integral

e^{(- x^{2})}

\frac{π}{2} erf (x) + C

Solution steps

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

Use the nonelementary integral:

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

= \frac{π}{2} erf (x)

Add a constant to the solution

= \frac{π}{2} erf (x) + C

\int \frac{sin ( 2 x )}{y} d x

\int \frac{4 - x}{( x + 2 ) ^{2}} d x

\int h^{\frac{1}{2}} d h

\int (csc^{2} (x) + 9) d x

\int \frac{1}{16 e ^{- 8 x} + e ^{8 x}} d x
