$\ln u!\sim\ln\sqrt{2\pi u} + u\ln u - u$

\ln u!\sim\ln\sqrt{2\pi u} + u\ln u - u

(ID 4737)

$u!\sim\sqrt{2\pi u}\left(\displaystyle\frac{u}{e}\right)^u$

u!\sim\sqrt{2\pi u}\left(\displaystyle\frac{u}{e}\right)^u

(ID 8966)

$e^z\sim\left(1+\displaystyle\frac{z}{u}\right)^u$

e^z\sim\left(1+\displaystyle\frac{z}{u}\right)^u

(ID 8967)

$\ln(1+u)= u-\displaystyle\frac{1}{2}u^2+O(u^3)$

\ln(1+u)= u-\displaystyle\frac{1}{2}u^2+O(u^3)

(ID 9000)

$1+u\sim e^{u-\frac{1}{2}u^2}$

\ln(1+u)= u-\displaystyle\frac{1}{2}u^2+O(u^3)
