e^(i*pi) (idea)

This is usually written as

e^iπ+1=0

so that it has all the important numbers:

e the base of the natural logs.
i the square root of minus one.
pi the ratio of the circumference to the radius of a circle.
0: nothing.
1: unity.

mblase: thanks for telling me about &#928., but it works as well as π does. It just gives a block on Opera on my machine. D'Oh!
