simplify arctan(x)-1/(2(x^2+1))

simplify

arctan (x) - \frac{1}{2 ( x ^{2} + 1 )}

\frac{2 x ^{2} arctan ( x ) + 2 arctan ( x ) - 1}{2 ( x ^{2} + 1 )}

Solution steps

arctan (x) - \frac{1}{2 ( x ^{2} + 1 )}

Join

arctan (x) - \frac{1}{2 ( x ^{2} + 1 )} : \frac{2 x ^{2} arctan ( x ) + 2 arctan ( x ) - 1}{2 ( x ^{2} + 1 )}

= \frac{2 x ^{2} arctan ( x ) + 2 arctan ( x ) - 1}{2 ( x ^{2} + 1 )}
