Euler's identity is a direct result of Euler's formula, published in his monumental 1748 work of mathematical analysis, Introductio in analysin infinitorum, [16] but it is questionable whether the particular concept of linking five fundamental constants in a compact form can be attributed to Euler himself, as he may never have expressed it.
Euler's identity is a special case of this: e i π + 1 = 0 . {\displaystyle e^{i\pi }+1=0\,.} This identity is particularly remarkable as it involves e , π {\displaystyle \pi } , i , 1, and 0, arguably the five most important constants in mathematics, as well as the four fundamental arithmetic operators: addition, multiplication ...
Leonhard Euler (/ ˈ ɔɪ l ər / OY-lər; [b] German: [ˈleːɔnhaʁt ˈʔɔʏlɐ] ⓘ, Swiss Standard German: [ˈleɔnhard ˈɔʏlər]; 15 April 1707 – 18 September 1783) was a Swiss polymath who was active as a mathematician, physicist, astronomer, logician, geographer, and engineer.
Euler's formula is ubiquitous in mathematics, physics, chemistry, and engineering. The physicist Richard Feynman called the equation "our jewel" and "the most remarkable formula in mathematics". [2] When x = π, Euler's formula may be rewritten as e iπ + 1 = 0 or e iπ = −1, which is known as Euler's identity.
Euler's identity e iπ + 1 = 0. Euler's four-square identity, which shows that the product of two sums of four squares can itself be expressed as the sum of four squares. Euler's identity may also refer to the pentagonal number theorem.

In addition to Euler's identity, it can be helpful to make judicious use of the real parts of complex expressions. For example, consider the integral For example, consider the integral ∫ e x cos x d x . {\displaystyle \int e^{x}\cos x\,dx.}
