[edit] Relation to Euler's formula
This mathematical term forms part of an identity, a special case of Euler's formula, written eix = cos(x) + isin(x). Setting x to a value of π, as with the above term, Euler's formula reduces to a famous equation relating five important mathematical numbers, namely eiπ + 1 = 0.
