在数学中有两个重要的无理数:π和e.我们知道π是圆的周长与直径之比,那么e又是怎样定义的呢?lnx为什么叫自然对数?在高中学习了指数函数和对数函数后,就初识了无理数e,对e,ex,lnx,中学生往往有神秘莫测之感,下面我们就来谈谈这个问题.1两个实例1.1连续复利约翰·贝努利在他的?
There are two important irrational numbers in mathematics: π and e. We know that π is the ratio of the perimeter to the diameter of a circle, so how e is defined? Why lnx is natural logarithm? Logarithmic function, we first know the irrational number e, e, ex, lnx, middle school students often have the feeling of mystery, we will talk about this problem .1 two instances of 1.1 continuous compound interest John Bernoulli his?
