MMeden Agan replied to the thread I Schrödinger equation and classical wave equation.Yes, but I mean: the classical wave equation has two derivatives in time and two derivatives in position; the Schrödinger equation has...

MMeden Agan replied to the thread I Schrödinger equation and classical wave equation.Yes. AFAIK, Schrödinger developed his equation through an admirable reverse engineering operation, starting from the analogy between the...

MMeden Agan reacted to Demystifier's post in the thread I Schrödinger equation and classical wave equation with
Like.
Schrodinger didn't know what is the physical meaning of the wave. He only used the nonrelativistic energy formula $$E=\frac{p^2}{2m}+... -
MNot an expert in QM. AFAIK, Schrödinger's equation is quite different from the classical wave equation. The former is an equation for...

MMeden Agan reacted to mathwonk's post in the thread How can we teach students the difference between sequences and series? with Like.
Perhaps the answer is contained in your first point. I.e. perhaps one should teach sequences first and thoroughly, and only treat...

MMeden Agan posted the thread How can we teach students the difference between sequences and series? in STEM Educators and Teaching.Sequences and series are related concepts, but they differ extremely from one another. I believe that students in integral calculus...

MMeden Agan reacted to fresh_42's post in the thread Is mathematics invented or discovered? with Like.
I am, and many mathematicians are, too, a Platonist. It is discovered. I even go as far as thinking that great compositions or paintings...

MMeden Agan replied to the thread Prove that the integral is equal to ##\pi^2/8##.@fresh_42 Did you get something new?
-
MThe question ‘is mathematics invented or discovered?’ is a much-debated issue in the philosophy of mathematics. It is a classic. I would...

MMeden Agan replied to the thread Prove that the integral is equal to ##\pi^2/8##.I don't see how that helps either. Let me know if you get anything useful, I'm stuck.

MMeden Agan reacted to fresh_42's post in the thread Prove that the integral is equal to ##\pi^2/8## with Like.
I found some nice formulas, e.g., with ##y^2=9-16x## we get $$ \dfrac{(x-1)\left(x-1+x\sqrt{9-16x}\right)}{1-2x}=...

MMeden Agan replied to the thread Prove that ##\lim\limits_{x \to \infty} f(x) = 0##.Mhm, could you outline what's unclear step by step? Hope I can provide a detailed clarification.

MMeden Agan reacted to nuuskur's post in the thread Prove that ##\lim\limits_{x \to \infty} f(x) = 0## with Like.
A point to consider is why the function is well defined, i.e, why does the minimum exist for ##x>0##. (If it doesn't then change minimum...
