簡約 (1/2 arctan(x/2)+c)/8+x/(8(x^2+4))

解

簡約

\frac{\frac{1}{2} arctan ( \frac{x}{2} ) + c}{8} + \frac{x}{8 ( x ^{2} + 4 )}

\frac{2 c + arctan ( \frac{x}{2} )}{16} + \frac{x}{8 ( x ^{2} + 4 )}

解答ステップ

\frac{\frac{1}{2} arctan ( \frac{x}{2} ) + c}{8} + \frac{x}{8 ( x ^{2} + 4 )}

簡素化

\frac{\frac{1}{2} arctan ( \frac{x}{2} ) + c}{8} : \frac{2 c + arctan ( \frac{x}{2} )}{16}

= \frac{2 c + arctan ( \frac{x}{2} )}{16} + \frac{x}{8 ( x ^{2} + 4 )}
