The number e (e = 2.718...), also known as Euler's number, which occurs widely in mathematical analysis The number i , the imaginary unit such that i 2 = − 1 {\displaystyle i^{2}=-1} The equation is often given in the form of an expression set equal to zero, which is common practice in several areas of mathematics.
r = | z | = √ x 2 + y 2 is the magnitude of z and; φ = arg z = atan2(y, x). φ is the argument of z, i.e., the angle between the x axis and the vector z measured counterclockwise in radians, which is defined up to addition of 2π. Many texts write φ = tan −1 y / x instead of φ = atan2(y, x), but the first equation needs ...

The designation E 8 comes from the Cartan–Killing classification of the complex simple Lie algebras, which fall into four infinite series labeled A n, B n, C n, D n, and five exceptional cases labeled G 2, F 4, E 6, E 7, and E 8. The E 8 algebra is the largest and most complicated of these exceptional cases.
