Speaking of infinity, I think 0^0= -0, which is infinity... for it is beyond definition....

Well...... sometimes it works, your right I did not try it enough. I think i'll erase that...

#132 Re: Help Me ! » 4 kissing circles » 2013-01-25 23:26:12

roflol I'm thinking you stole my idea because I did the same thing on a thread of 3 kissing circles with bobbym.
And the 4 circles etc. is for my upload on the GeoGebra Forum and on this site where you can upload GeoGebra programs.

This is obvious. Has anyone noticed that 2013 has 0, 1, 2, and 3.

#138 Re: This is Cool » Prime Numbers!! » 2013-01-25 12:02:14

Prime numbers are numbers that have no other factors then one and itself. One is not a prime number... 1x1=1 and 1/1=1.
x = prime
y = anything other than 1 and x
z = composite
a = decimal
x/1=x. x/x=1. x/y=a.
z/1=z. z/z=1. z/y=y.
For something else on prime numbers... go to my Sieve of Eratosthenes post.

Here's the Sieve of Eratosthenes, the strategy of an ancient Greek mathematician to find prime numbers.
So, x=2, the first prime number. Write a list of numbers from x to y.
Cross out x's multiples, then do the same for the next uncrossed number. The ones crossed out are the composites, and the ones left are the primes, because primes have no factors other than 1 and itself, and composites have at least one more. so if y = 10, then the primes are:
2, 3, 5 and 7,
and the composites are:
4, 6, 8, 9, and 10.

I figured that 100! is somewhere around...
654,747,700,701,377,386,126,856,657,861,679,570,529,800,895,801,424,573,182,559,133,258,946,484,061,065,580,876,771,978,236,269,380,302,819,031,314,362,546,968,961,704,181,923,607,153,180,171,236,969. That's QUINDECILLIONS!

#141 Re: This is Cool » I've Reached Infinity! 2 » 2013-01-25 11:13:28

So...
on GeoGebra, 6.5e9 is
20,711,912.8 units?

Can we continue the thread here?
Anyway, 100! equals
9.332622e157.
What is e?
Speaking of e... I got E on GeoGebra, I zoomed out and it ended up with 6.5E9. I know thats greater than 1,000,000 units, because I passed that.

#144 Re: Coder's Corner » EndIf is If? » 2013-01-24 09:03:22

I didn't get that last part; but thanks for the explanation on ElseIfs.

#145 Re: This is Cool » I've Reached Infinity! » 2013-01-24 08:59:36

It wont let me check the max value; and I swear I saw the infinity sign.

#146 Re: Coder's Corner » EndIf is If? » 2013-01-24 00:04:28

ElseIfs... Sure! It was like this...

TextWindow.WriteLine("Testing")
test = TextWindow.Read()
If test = "Testing Reply" Then
  TextWindow.WriteLine("This is text.")
ElseIf
test2 = TextWindow.Read()
If test2 = "Testing Reply 2" Then
  TextWindow.WriteLine("This is also text.")
Else
  TextWindow.WriteLine("Sorry, this operation did not perform correctly.")
EndIf

And it never works!

Well, the Nexus 7 Calculator app was wrong... I'm sure I saw infinity on there.0

I found another equation, which ends

Remember my sin, on, cos, etc. equation?

Someone fix my LaTex; I'm not so familiar with it.

I agree with you, mathgogocart.
The ANCIENT GREEKS INVENTED IT IN THE ERA OF BC!
