[edit] Summary

English: Stub image for the Math-stub template on Wikipedia. Shows part of Euler's identity.

Image made by myself in en:Inkscape. Provides a vector version for Image:E-to-the-i-pi.png. Because it uses no fonts, should render up in any system.

[edit] Relation to Euler's formula

This mathematical term forms part of an identity, a special case of Euler's formula, written $e i x = cos(x) + i sin(x)$ . 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 $e i π + 1 = 0$ .
