Re: How to determine .......
Don't waste your time,this is an expression that is notorious for not having a closed form solution.
This function does not have an elementary integral, just as e^(x^2) and sin(x)/x do not.
Yo can stimate it using Riemann sums, Simpsons method or any standard...
Re: Where does the natural logarithm constant "e"
e is the unique number with the property that the area of the region bounded by the hyperbola y=1/x , the x-axis, and the vertical lines x = 1 and x = e is 1. In other words:
/ e
