Euler’s identity is often considered one of the most beautiful formulas in mathematics.

It connects the constants , , , , and in a single equation, and can be interpreted geometrically on the complex plane .

For example, the inline fraction , the derivative , and the limit can all be written directly inside a sentence.

When , we get

and therefore

Here is a more complicated derivative expression:

We can also display matrices, cases, and integrals:
