18.75 (1 - e^{- 0.91 (t + 0.01)})

18.75 - 18.75 e^{- 0.91 t - 0.0091}

求解步骤

18.75 (1 - e^{- 0.91 (t + 0.01)})

使用分配律:

a (b - c) = ab - a c

a = 18.75, b = 1, c = e^{- 0.91 (t + 0.01)}

= 18.75 \cdot 1 - 18.75 e^{- 0.91 (t + 0.01)}

= 1 \cdot 18.75 - 18.75 e^{- 0.91 (t + 0.01)}

化简

1 \cdot 18.75 - 18.75 e^{- 0.91 (t + 0.01)} : 18.75 - 18.75 e^{- 0.91 t - 0.0091}

= 18.75 - 18.75 e^{- 0.91 t - 0.0091}
