Euler's
Formula
e^{iπ} + 1 = 0.
This remarkable equation combines e, i, π (pi),
1, and 0, which are arguably the five fundamental numbers of
mathematics. It also includes addition, multiplication, exponentiation,
and composition, four of the fundamental operations of mathematics.
Note: Euler is pronounced "Oiler".
