You may immediately recognize that this limit is #1#, since the #e^x# terms in the numerator and denominator will overpower the other terms, so as #x# approaches infinity, #(e^x+1)/(e^x+x)approxe^x/e^x=1#, but in case this isn’t enough for you we can do L#oo

11/6/2009 · But the t=lnx function is defined by that it is the inverse of y=e^x, which is defined by that e=lim h –> h (1+h)^(1/h) so basically it is circular logic. The definitions must start somewhere. You can though find a different definition of e, and then connect these links.

As functions of a real variable, exponential functions are uniquely characterized by the fact that the growth rate of such a function (that is, its derivative) is directly proportional to the value of the function. The constant of proportionality of this relationship is the natural logarithm of the base b: d d x b x = b x

Like all logarithms, the natural logarithm maps multiplication into addition: ln ⁡ x y = ln ⁡ x + ln ⁡ y . {\displaystyle \ln xy=\ln x+\ln y.} Logarithms can be defined for any positive base other than 1, not only e. However, logarithms in other bases differ only by a constant multiplier from
