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

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

e^{a r c t a n (y)} + C

Solution steps

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

Apply u-substitution

= \int e^{u} d u

Use the common integral:

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

= e^{u}

Substitute back

u = arctan (y)

= e^{a r c t a n (y)}

Add a constant to the solution

= e^{a r c t a n (y)} + C
