    Unusual set of 3 integers

    I fail to see how this is inconsistent with Mathematics in general!

    Proof Practice

    You might start by trying to prove some statements about parity. Like an odd number times an odd number is always odd. Even number times anything is always even. Those are pretty straight forward. If you feel you already feel comfortable with those. Then really you should just find a good...

    Proof Practice

    Also, if you scroll through the Calculus and beyond section you might find some exercises to try to prove. Or.. you might prove that there are no positive integers ##a,b,## and ##c## such that for ##n \geq 3## $$a^n + b^n = c^n$$. :-p

    A lunch at Golden Corral you say? Well.. go on..

    Largest Known Prime

    Yeah, I think the problem is you can't possibly test all values for n. But if you are asking about the expression I posted in the op, that doesn't always work and simply describes the form of a specific type of prime number.

    Largest Known Prime

    Whether it was proven that one cannot exist I'm not entirely sure, but as fas as application, there is a foundation offering a substantial sum of money to find one, 1 million dollars I think? :)

    Largest Known Prime

    That doesn't sound completely "not-fun" but alas I don't have an over abundance a time And while I did get a free Mathematica license from my school I haven't installed it yet because my computer is well.. sub-par. :) maybe this summer..

    Hey, I was just posting what I read and learned from that talk, lol.

    Largest Known Prime

    This news is a little dated, but I still found it interesting and wanted to see what everyone else thought about this years discovery of a new "largest" prime: ##2^{(57,885,161)}-1## its 17,425,170 digits long and would span all 7 harry potter books twice. Written out in plain text it would take...

    A way to express scalar triple product from inter-vector angles?

    Could you give an example of what you have?(the vectors) If I can't manually solve them, I may be able to help you punch them into mathematica.

    Plotting 3d graphs

    Depending on how much you mind paying. Mathematica is top of the line but has a hefty price tag, and can be a bit cumbersome. If you want something that is free, a little more user friendly, but much less "elegant." Winplot is good. On a side note, many college campuses have Mathematica in...
