    This must be too far over my head for me to understand. http://functionspace.org/articles/6/Understanding-the-most-beautiful-equation-in-Mathematics[Understanding the most beautiful equation in Mathematics] My head was swimming after reading through the whole article and then it came down to:

    Quote:

    If we put, x=π , we get: eiπ = −1 as cosπ = −1 and sinπ = 0 or eiπ + 1 = 0

    Ahhh, ok... but doesn't all that just mean: -1 + 1 = 0 ??? :wtf:

    Yes, but you are missing the point. The main thing to prove here is that eiπ = -1, this is the nontrivial part.

      one might also say that eiπ = cos(π) ;P

        And the fact that eiπ = -1 seems somehow significant, almost metaphysical... :rolleyes:

                The link isn't opening but I'm guessing that this one is probably over my head too. Most likely it comes down to something like: 0 = 0 1 = 1 2 = 2 ... :laugh:

                              The awesome thing about this equation is that three apparently unrelated constants, from entirely different areas of mathematics (calculus, geometry and complex numbers), can be related in such an elegant and simple way.

                                  Yes, of course it is mysterious, metaphysical and non-trivial, yet very true. Therein lies its beauty.

                                          ;P Nothing personal against you intended - I was more interested in mathematicians as a breed (unless you are a mathematician, in which case...).
