0.75 (1 - e^{- 100 t})

0.75 - 0.75 e^{- 100 t}

求解步骤

0.75 (1 - e^{- 100 t})

使用分配律:

a (b - c) = ab - a c

a = 0.75, b = 1, c = e^{- 100 t}

= 0.75 \cdot 1 - 0.75 e^{- 100 t}

= 1 \cdot 0.75 - 0.75 e^{- 100 t}

数字相乘:

1 \cdot 0.75 = 0.75

= 0.75 - 0.75 e^{- 100 t}

e x p an d - \frac{9}{4} + \frac{1}{4} x

e x p an d \frac{24}{( 8 + x ) ^{2}}

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