解答

展开

\frac{2.33 x ( 1.2 - 0.6 y )}{1 - 0.4 x}

\frac{2.796 x - 1.398 x y}{1 - 0.4 x}

求解步骤

\frac{2.33 x ( 1.2 - 0.6 y )}{1 - 0.4 x}

乘开

2.33 x (1.2 - 0.6 y) : 2.796 x - 1.398 x y

= \frac{2.796 x - 1.398 x y}{1 - 0.4 x}

e x p an d x + h (x + h)

e x p an d 10 (e^{x} (cos (3 x) + 4 sin (3 x)))

e x p an d 9 + 6 x^{- \frac{1}{2}}

\frac{d}{d a} ((Y (a, b, T)) (a + b (Y (a, b, T) - T)))

e x p an d \frac{- e ^{t} ( t + e ^{t} ) - ( - 1 + t e ^{t} ) e ^{t}}{9}
