记住,这些近似公式是线性近似。
Remember, these approximation formulas, they are linear approximations.
它方便我们记住近似公式。
当然,我们已经见到了一些别的近似公式。
Well, of course, we've seen other approximation formulas and so on.
To actually apply this it helps to go to something called the normal approximation to the binomial, because it's kind of difficult to compute this formula.
在实际应用这些公式的时候,需要运用二项分布的正态近似定理,因为二项分布公式的值很难计算
