Question

Euler in Mathcad

Mathcad has many functions and constants named after mathematicians and scientists - Chebyshev, Runge, Kutta, Kelvin, Sinus, Ampere, etc.
But I did not find there the name of the greatest mathematician - Euler. We need to fix this and make the Euler function built-in Mathcad for the simplest numerical solution of the ODE.
Especially now, due to the high calculation speed, there is a return to simple algorithms - KISS!

Sinus?

Its not named after a mathematician or scientist!

Sinus comes from the latin word sinus, which means:    bay,    gulf,    bent surface,    lap,    bosom,      breast.

Especially that last translation gives special meaning to cosinus...

Sorry, I put Sinus on the list on purpose to test you! This is what I sometimes do with my students to see if they are following my lecture.😉

When I was a student, the first classroom equipped with TVs appeared at my university. It was an electrical engineering classroom. On this occasion, even a note appeared in the main Soviet newspaper. The note ended like this: "The lecturer presses a button and a Hysteresis loop appears on the TV screen." The word hysteresis was capitalized. Colleagues approached this lecturer and asked: "How is old Hysteresis doing there?"

According to Wikipedia, Euler has a number, a constant and a characteristic named after him:

Euler's number is: e=2.718...

Euler's constant is: gamma=0.5772

Euler's characteristic is: 2, the sum of the numbers of vertices and faces minus edges of a polyhedron.

In Wikipedia but not in Mathcad 😪

It will be good to have Euler built-in function for ODE solution in Mathcad.

Not for using but for memory! 

A propose

In Russia e=2.7 1828 1828... is a Leo Tolstoy constant. This writer was born in 1828.
