comment Is it possible that “A counter-example exists but it cannot be found”
Do you have an example of a hypothesis that is known to be false (by some proof other than showing a counterexample), but for which the counterexample is difficult to find?

comment Is it possible that “A counter-example exists but it cannot be found”
What evidence is there that the counterexample exists if it cannot be found, and how is that evidence convincing if it does not amount to producing the counterexample?

comment Is this already an equation/law that has been found?
It occurs to me that Gauss' teacher might have been the first person whose attempt at creating a software delay loop was foiled by optimization!

comment What is the equation for a tangent to the graph of $y=\arcsin(x/2)$ at the origin?
Have you looked in the Wikipedia? en.wikipedia.org/wiki/…. The derivative of Arcsin is right there in a table. For x/2 you can apply the rule that f'(Cx) = Cf'(x).

comment Visually stunning math concepts which are easy to explain
Whereas complex numbers might not be easy to explain, it is easy to explain the idea idea that each pixel is calculated by repeating a simple calculation on two numbers (which are initially the coordinates of the pixel), and the color is a measure of how the resulting pair of numbers "escapes" (grows large).

comment Prove the right triangle identity: $\frac a A = \frac b B = \frac c C$
The main issue here is that when you scale a space horizontally and vertically by the same factor, then every direction scales by the same factor, including all possible diagonals.

Good answer and of course "would you be okay with this" is the most important question: what does OP accept as axioms? Where is bottom?

comment What's the algebraic property where you can flip the fractions in an equation?
There is no such algebraic property. Now both sides of an equation can be reciprocated (for values of variables such that the sides of the equation are not zero). However, that is not an algebraic property, but simply the consequence that both sides of an equation denote the same number, and the same operation is done to that number on both sides. Algebraic properties usually tell us that certain apparently different patterns of operations are actually equivalent.

comment Is the number 100k+11 ever a square?
@hunter I would scratch the word "like" in that sentence on the grounds that it is a "valley speak" hedge word with no meaning.

comment How to calculate square root or cube root?
@abiessu I think amaach means a trial-and-error way of calculating the root simply by guessing at the root, cubing or squaring it, and adjusting the guess larger or smaller. If you keep doing that, instead of switching to a better algorithm, you will not improve your mechanisms.
