This forum needs to be alive. Honestly, surely the mathematical community of the chess.com is greater than the one here. Or maybe they've all migrated to lichess? It's the worst Gauss I could possibly make.

QED

 

Don't put QED at the end of a proof, put the Halmos symbol for ultimate simplicity, actually, make that complexity, simplicity anddd... we're left with an infinite regress. Not my fault.

They migrated to the 11th dimension and all. You'll always have Sun Wukong (myself) marching by your side!

Everybody's done the tan versus sec^2 trade and and half calc hornbook problem, where you move across the equality to use more blunt tools.  But is there intuition to be had from this problem that bleeds over to the more axiomatic probabilities and combinatorics via the hyperbolics?  Can we use transforms in games of chance is ultimately my question?

The function isn't injective with f(0) being equal to f(1), meaning it cannot have an inverse, not being one to one and onto. But if you specify a right interval of x being less than or equal to 1/2, then you rearrange the equation to x^2-x-y=0, and the quadratic equation says it all.

I do not understand the pretext of your question.

Has no-one mentioned the Legend of Question 6 from the 1988 IMO? Surely, someone with an appreciation for number theory will have mentioned it.

math is extremely useless. when have you ever used math? when will you ever use math? never. it is just an excuse to waste your life on when in reality you should be increasing your muscle mass to extraordinary levels

But if you go to the store and buy something and you don't know it costs too much...

 

What sadkid2008 had in mind was likely very distinct to elementary math. He was probably referring to the purest of the purity in the name of the study of the name of mathematics, beyond the cookbook math context of linear algebra. And on his part, I would have to partially agree... Although it is a thrill to work through some of the problems, I must agree.

How do you reconcile relativity with quantum theory?

 

Easy as pi sliced into infinitely many pieces (that's why renormalisation in the quantum exists, I suppose). Reconciling general relativity with quantum mechanics is indeed difficult, but with quantum mechanics and special relativity, there's a nicely smooth transition...

It has an inverse function, i solved it before.

instead of explaining things.. try to solve it, we both are aware of these informations.

Am I obligated to solve it? Well, if I desire.

1+sqrt(1+4x)/2

and

1-sqrt(1+4x)/2
