integral of 3^{x^2}

\int 3^{x^{2}} d x

\frac{π erfi ( x ln ( 3 ) )}{2 ln ( 3 )} + C

Solution steps

\int 3^{x^{2}} d x

Use the nonelementary integral:

\int 3^{x^{2}} d x = \frac{π erfi ( x ln ( 3 ) )}{2 ln ( 3 )}

= \frac{π erfi ( x ln ( 3 ) )}{2 ln ( 3 )}

Add a constant to the solution

= \frac{π erfi ( x ln ( 3 ) )}{2 ln ( 3 )} + C

\int 3 x + \frac{3}{5} d x

\int \frac{x + 1}{x ^{2} - 4 x} d x

\int 12 sec (2 x) tan (2 x) d x

\int ln^{2} (x^{20}) d x

\int csc (1 - 5 x) d x
