解答

展开

- \frac{x}{ln ( x + 1 ) ( x + 1 ) + x}

- \frac{x}{x ln ( x + 1 ) + ln ( x + 1 ) + x}

求解步骤

- \frac{x}{ln ( x + 1 ) ( x + 1 ) + x}

乘开

ln (x + 1) (x + 1) + x : x ln (x + 1) + ln (x + 1) + x

= - \frac{x}{x ln ( x + 1 ) + x + ln ( x + 1 )}

e x p an d (1 + 2 cos (2 x))^{2}

e x p an d \frac{π ( e ^{- s} + 1 )}{( s ^{2} + π ^{2} ) ( s ^{2} + 1 )}

e x p an d (\frac{1}{2} - 2 p)^{2}

e x p an d 1 - 2 x (1 - 2 x)
