- If you can’t get it to simplify, try eulering the equation.

## euler

verb; zero derivation

To change sine and cosine to complex numbers, or the reverse operation. As an electrical engineering, we often have large problem sets to complete each week. Therefore, we get together the night before it is due to help each other and check answers. As the night progresses, we become more and more tired and we want to leave as soon as possible. When one wishes to change from a sine or cosine to complex numbers, one would say “use Euler’s method”. One of the more painful parts of our homework is often simplifying our answers, and this can be done using Euler’s method. However, since we are already exhausted and want to go to bed, we can get ideas across much faster by shortening the phrase “to use Euler’s method” to just “to euler”. As a result, this is an eponymy of Leonard Euler, the mathematician who invented this shift of trigonometric functions to complex numbers.

Etymology : Zero derivation from euler method, eponymy of Leonard Euler
