May 20, 2015 · A constant is something like a "number". It doesn't change as variables change. For example $3$ is a constant as is $\pi$. A parameter is a constant that defines a class of equations. $$\left(\frac xa\right)^2 + \left(\frac yb\right)^2 = 1$$ …

A constant is 0-ary function into some codomain. It is often better to talk about a "constant in X" to specify which codomain X is being discussed, as that often determines it's properties with respect to the rest of an expression. A constant is often represented by the element of the codomain that the 0-ary function evaluates to.

To actually explain it to somebody not so math-literate: e is the constant of growth. Whenever you want to relate the future value / quantity of something to now, thus define the future as a function of the present or vice versa, the only way to do this constantly and continuously is with e.

Jun 26, 2021 · Kaprekar's constant, or 6174, is a constant that arises when we take a 4-digit integer, form the largest and smallest numbers from its digits, and then subtract these two numbers. Continuing with this process of forming and subtracting, we will always arrive at the number 6174. 6174 is known as Kaprekar's constant after the Indian mathematician ...

Jul 14, 2015 · Formally speaking, the right way to doing it would be to write something like $$\int 2x\, \mathrm{d}x = x^2 + k, \ \text{where } k \text{ is constant}$$ If you did insist on doing it that way, to me it would look weird if it was italicised: italicised letters inside equations or formulae are usually interpreted as variables, so you technically end up with some ambiguity if any of the …

In the special case of a constant path, instead of ever moving a single inch you just sort of..... stand there, for the whole time. $\endgroup$ – Lee Mosher Commented Jan 27, 2017 at 17:59

Feb 5, 2018 · You should be careful - as written, your claim is not quite correct. The zero-curvature condition $\nabla^2 = 0$ is the definition of flatness of the connection $\nabla$.

How to prove that by performing Kaprekar's routine on any 4-digit number repeatedly, and eventually we will get the 4-digit constant $6174$ rather than get stuck in a loop, without really calculating
