Proof of Eulers formula

less than 1 minute read

Published:

As we know Euler’s fomula is very ubiquitous in mathematics, physics, and engineering. The fomula is as follows:

[e^{i\theta}=\cos(\theta)+i\sin(\theta)]

I never though how to prove this formula until seeing a simple proof with an interesting story behind in the book “Linear Algebra and Its Applications”, Gilbert Strang. One day there was a letter came to MIT from a prisoner in New York, asking if Euler’s fomula was true? It is really astonishing. Three key functions of mathematics come together in such a graceful way.
