彩色的定义

number_e

\newcommand{\growth}{\color{c1}} \newcommand{\naturallog}{\color{c2}} \newcommand{\unitInterest}{\color{c3}} \newcommand{\timetogrow}{\color{c4}} \newcommand{\unitTime}{\color{c5}}\displaystyle{\naturallog \ln(a) \plain = \timetogrow \ int_ {1}^{a} \unitInterest {\frac {1}{x}} dx}\displaystyle{\naturallog \ln(\growth{e} \naturallog) \plain = \unitTime 1}自然对数是使用unitInterest 100 % continuous interest从1增长到一个值的时间。e是需要自然对数unitTime 1个单位时间才能达到的数字。
