求解步骤

\frac{( - 7 - 6 j ) ( - 4 + 2 j )}{( - 4 - 2 j ) ( - 4 + 2 j )}

约分:

- 4 + 2 j

= \frac{- 7 - 6 j}{- 4 - 2 j}

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

e x p an d \frac{3 e ^{4 π s} s}{( s ^{2} + 4 ) ( s ^{2} + 16 )}

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

e x p an d \frac{3125 ( 10 π + 3 3 )}{32} - \frac{875}{6}

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