Tenchusatsu,

When you have a ratio of functions that evaluates to 0/0, what you could do is differentiate both the numerator and the denominator, then calculate the results using the newly derived formulas.

That's a good answer. I tested it on (x - 1) / (X^2 - 1) which is 0 as x approaches 1. Differentiating I get 1 / 2, which is 0.5

I put together a simple Excel spreadsheet, by starting form 0.9, and incrementing by previous result + (1 - previous result) / 2, the ratio of the functions do converge to 0.5

Joe

"if you understood every word of what I just said"

Yeah, you forgot few words, that the functions must be differentiable...

re: Of course, if you understood every word of what I just said, join me this weekend

wow, you went to high school after all :-))

here is a grade school problem:

if sum = 1.5 + 1.5^2+....+1.5^x where x -> infinity

then what is sum / (1.5* sum)

ps if it would take you more than a sec to solve it then quit geeks_r_us.org
