expand (dx)/((1+x^2)arctan(a))

expand

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

\frac{d x}{arctan ( a ) + x ^{2} arctan ( a )}

Solution steps

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

Expand

(1 + x^{2}) arctan (a) : arctan (a) + x^{2} arctan (a)

= \frac{d x}{arctan ( a ) + x ^{2} arctan ( a )}

(e^{x} - x) d x

\frac{- 5 - x}{( x + 9 ) ^{2}}

\frac{( 2 s - 8 )}{( s - 2 ) ( s - 3 )}

\frac{x - 6}{( x - 5 ) ( x + 3 )}

e^{2 - t} \cdot U (t - 2)
