i know its a bit of a wierd question but you people are very knowledgable, does any1 know how to figure out the squre root of a number?
include cmath
use sqrt()
remind me agen, how can i extract sums from libs?
Scratch that: sqrt=pow(number,0.5)
i need to write a power function now :confused:
>>i need to write a power function now
Then search the boards, there's sample code out there. Or simply write your own.
Does anyone here actually know the precise formula to find the square root of a number? I'm not neccessarily looking to find out how to do it (I could easily find the answer myself), but to see if someone knows the formula for it. My math teahcer said she used to know, but she hasn't used it in so long that she forgot what it is.
Davros, I don't particularly care to know the formula myself, yet to see if someone had the formula memorized themself.
you find the square root of a number by mulptliging a number by it self, the perfect quares in math are as fallowsQuote:

0=0
1=1
2=4
3=9
4=16
5=25
6=36
7=49
8=64
9=81
10=100
11=121
12=144
i know up to 15 but i jsut forgot them :)
No, that's the square of the number.Quote:

Do I detect a bit of sarcasm?
Wowzers! I gotta tell my math teachers about this! I gotta find all of them since my 4th grade class! I must tell them that they taught me the square root wrongly! Haha! I can't wait to see the looks on their faces!Quote:

This is taught to first year plumber and pipefitter appretices which is also how I was taught in school. It is rather convoluted though:

typo's again

I dont know what convoluded means but it sure it complicated
