Seconded! Fredrik is a hero.

Favorite line:

"Euler's formula... Discovered around 1740 by the Swiss Sorcerer Supreme, Leonhard Euler, this formula can transmute exponentials into trigonometric functions and vice versa. A magic formula indeed!"

Indeed! (And a mathematical IDENTITY... as are many others in this "Grimoire"...)

Great work, Fredrik!

And earlier published in 1714 by the Englishman Roger Cotes.
