Really cool thing with the numbers like a^xHere is what we do: Last edited by krisper (20060115 07:47:46) Humankind's inherent sense of right and wrong cannot be biologically explained. #2 20060115 05:06:29
Re: Really cool thing with the numbers like a^xThat only works when x is a positive integer. Last edited by mathsyperson (20060115 10:28:29) Why did the vector cross the road? It wanted to be normal. #3 20060115 06:12:52
Re: Really cool thing with the numbers like a^xThanks for your reply mathsyperson. Humankind's inherent sense of right and wrong cannot be biologically explained. #4 20060115 06:31:17
Re: Really cool thing with the numbers like a^xIt doesn't work with x=0 either. For that, you get a Z value of 1. Why did the vector cross the road? It wanted to be normal. #5 20060115 07:20:36
Re: Really cool thing with the numbers like a^xWhen is 0 you will get Z=1 and 0! equals 1, so n can be 0 And you are right again, it is only for integers because n! formula can only be used for integers that are >=0.

Re: Really cool thing with the numbers like a^xFrom Excel: Code:x=4 1 1 2 16 15 3 81 65 50 4 256 175 110 60 5 625 369 194 84 24 6 1296 671 302 108 24 0 7 2401 1105 434 132 24 0 8 4096 1695 590 156 24 0 9 6561 2465 770 180 24 0 10 10000 3439 974 204 24 0 And for x=5 you need an extra column to reach 0 "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."

Re: Really cool thing with the numbers like a^x
Oh! Sorry! When I read your original thing about Z=x!, I inferred that that was an exclamation mark, but now after reading MathsIsFun's post I realise that it was actually a factorial sign. Sorry again! Why did the vector cross the road? It wanted to be normal.
