Re: the square root of e?
Hi rogerkitkit;
Start with the Taylor series of e^x:
Now just substitute x = 1/2 and you are done.
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
