解答

展开

d x (\frac{e ^{- \frac{2 x}{L}} w ^{3}}{6} + Cw + C)

\frac{e ^{- \frac{2 x}{L}} w ^{3} d x}{6} + Cw d x + C d x

求解步骤

d x (\frac{e ^{- \frac{2 x}{L}} w ^{3}}{6} + Cw + C)

打开括号

= d x \frac{e ^{- \frac{2 x}{L}} w ^{3}}{6} + d x Cw + d x C

= \frac{e ^{- \frac{2 x}{L}} w ^{3}}{6} d x + Cw d x + C d x

乘

\frac{e ^{- \frac{2 x}{L}} w ^{3}}{6} d x : \frac{e ^{- \frac{2 x}{L}} w ^{3} d x}{6}

= \frac{e ^{- \frac{2 x}{L}} w ^{3} d x}{6} + Cw d x + C d x

e x p an d \frac{5 x - 2}{( 5 x + 4 ) ^{2}}

e x p an d \frac{4}{s ^{2} ( s ^{2} - 4 )}

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

s im pl i f y x (x^{2} - x + \frac{1}{6}) (x - \frac{1}{2})

e x p an d (sin (x) + cos (y)) (sin (y) - cos (x))
