Today I would like to reflect on my love for mathematics with asking the question: What is the most beautiful equation?
I was given my answer by my 9th grade physics teacher who said that Euler’s Identity is the most beautiful equation. Euler’s Identity is:
Notice how the equation uses 5 of the most important numbers in math and combines them into a nice clean equation. When he spoke to us about the idea of the most beautiful equation it was a weird concept to grasp. But Euler’s equation perfectly represented what I thought the most beautiful equation would look like.
The main use of Euler’s identity is to solve differential equations. It is also used to express trigonometric functions in exponential form.
I have attached a link that shows some of the other “most beautiful equations” in the link below. Which do you think is the most beautiful equation.
