integral of (2^{arctan(x)})/(1+x^2)

\int \frac{2 ^{a r c t a n (x)}}{1 + x ^{2}} d x

\frac{2 ^{a r c t a n (x)}}{ln ( 2 )} + C

Solution steps

\int \frac{2 ^{a r c t a n (x)}}{1 + x ^{2}} d x

Apply u-substitution

= \int 2^{u} d u

\int a^{x} d x = \frac{a ^{x}}{ln a}

= \frac{2 ^{u}}{ln ( 2 )}

Substitute back

u = arctan (x)

= \frac{2 ^{a r c t a n (x)}}{ln ( 2 )}

Add a constant to the solution

= \frac{2 ^{a r c t a n (x)}}{ln ( 2 )} + C
