Today at work, the famous "ei * pi
= -1" equation came up, and I wanted to search for its proof. Not knowing the name for it, I gave Google the query e i pi -1
. This gave me no search results, though, since it triggered Google Calculator. HA! The answer at first appeared to be wrong, but then I noticed it took the spaces to be multiplication, resulting in: (e * i
* pi) - 1 = -1 + 8.53973422 i
. On a hunch, I then searched for e^(i*pi) + 1
, and, sure enough, got the right answer.
Color me impressed. Does it do matrix math and quaternions, too?
