    Shout out to the euler relationship for allowing me to forget every single trig identity I ever learned

      I’d be curious how that works? I always hated memorizing those things, and I’d love it if there was some way to easily derive those from a single relationship.

        e^(ix) = cos(x) + i sin(x)

        That is the euler relationship. You can use that relationship to convert any expression with a trig function into an expression of exponentials and imaginary numbers. “Euler’s formula” is a good search term if you want to learn more

    I don’t know what any of those are, but surely lagrangian mechanics was invented by Lagrange, right

      Euler thought up or improved way too many things for them all to be named after him, it would get too confusing.

      From his wiki: “Euler’s work averages 800 pages a year from 1725 to 1783. He also wrote over 4500 letters and hundreds of manuscripts. It has been estimated that Leonhard Euler was the author of a quarter of the combined output in mathematics, physics, mechanics, astronomy, and navigation in the 18th century.” en.m.wikipedia.org/wiki/Leonhard_Euler

      And a relevant xkcd: Image

      I guess Euler-Langrangian mechanics was too much of a mouthful!

      An old bit of wisdom: “Most scientific concepts are named after the second person to discover them”

      hmmm… I was going to go with continuum mechanics as that seems made up. Maybe Euler contributed something to Lagrange.

        en.wikipedia.org/wiki/Continuum_mechanics

        Continuum mechanics deals with deformable bodies, as opposed to rigid bodies.

        I guess F = ma is pure Newton + Galileo.
