解答

展开

\frac{L}{P ( L - P )}

\frac{L}{L P - P ^{2}}

求解步骤

\frac{L}{P ( L - P )}

乘开

P (L - P) : L P - P^{2}

= \frac{L}{L P - P ^{2}}

e x p an d sin (π (m + \frac{1}{2})) - π cos (π (m + \frac{1}{2})) (m + \frac{1}{2})

e x p an d \frac{2 e ^{- s}}{s ^{3} ( s ^{2} + 1 )}

s im pl i f y (x - 1 + 10) (x - 1 - 10)

e x p an d (1 - y^{\frac{1}{3}})^{2}

s im pl i f y (p - 1 - p)^{2}
