Euler's Formula, named after mathematician Leonhard Euler, is a mathematical function that establishes the relationship between the trigonometric functions (sin and cos) and the complex exponential function (e to the power of i times x). Wear this Japanese math design and teach the world about complex analysis or buy it as a gift for your favorite Japan enthusiast or math otaku because mathematics is beatiful.

Euler's formula

Named after mathematician Leonhard Euler, Euler's identity is known as a prime example of mathematical beauty because it links the four most fundamental constants in mathematics: the circle constant pi, Euler's number e, the imaginary unit i, as well as the numbers 1 and 0. It also features three basic arithmetic operations: addition, multiplication and exponentiation. This Japanese-language design features the famous equation along with its Japanese name ("oiraa no toushiki"). Wear this design to show your appreciation for the beauty of mathematics or buy it as a gift for your favorite math otaku and Japan enthusiast because nothing is more beautiful than math.

This is one of the most beautiful results in mathematics, and it's often taught in introductory calculus courses.

Eulers Identity - The most famous mathematics equation

The beautiful equation, or the Euler equation of complex analysis, this bit of mathematics enjoys accolades across geeky disciplines. Swiss mathematician Leonhard Euler first wrote the equality, which links together geometry, algebra, and five of the most essential symbols in math -- 0, 1, i, pi and e -- that are essential tools in scientific work. Theoretical physicist Richard Feynman was a huge fan and called it a "jewel" and a “remarkable” formula. Fans today refer to it as “the most beautiful equation."

Also know as Euler's identity. It combines the numbers 0, 1, pi, e, and i in one equation.
