Show this to your kid. If they shiver, plan on spending a fortune for their PhD.
I got a bit of the shiver (I minored in math), but my dislike of homework was then and is now enough to keep me away from any danger of a PhD.
I even put the formula in Excel to watch it work. At n=170, it's off by .055194. At n=171, Excel can't handle the factorial.
I'll take your word for it. :lol2:
May give Monster a shiver.
