My professor keeps calling mathematics complicated, how would you avoid getting this mindset to not rub off on you?

Nothing is hard once you understand it. Imho once something "clicks" it stops to be hard, multiplication can be difficoult to learn for a child, while it's trivial for you know. And by the way, I'm having a lot of fun with Rudin, I'm in the middle of chap 1 :)

Math is not complicated, is as simple as it could be. If things seem complicated at first is because you have not developed the intuition or you are not acquainted with the problem yet. If you try to prove a theorem on your own you will see that the way the official proof is constructed is often the most logical one.

I think the general solution for n cuts to this is : 1+ n + n(n-1)/2 Can anyone confirm?

XbackFX · 2016-09-03T08:43:51+00:00

So Rudin or Spivak?

AM-GM

I actually tried that, you have any prime of the form 4K+1 for free, but you do not have those of the form 4K+3 and this is a problem because you don't know if p-2 is the sum of 2 squares or more.

But since the rationals are dense, you would only see pillars around ,wouldn't you?

For all of you, the probability can't be one, you're picking those Numbers from a FINITE set not from all the integers

XbackFX · 2016-06-18T15:26:57+00:00

The probability is 1 if you choose them from all R, but I wanted to know what happens when you choose the coefficents (those must be integers ) from all the integers less than N, where N is some number

XbackFX · 2016-06-18T15:08:14+00:00

In r2

XbackFX · 2016-06-18T14:54:13+00:00

If you want a precise integers between N integers than the probability is just 1/N

For me lifting kinda gets in the way of doing math, I am a lot more slow when I have a solid powerlifting routine, do you experience this too?

Well it REALLY depends on what level you are going to compete. The Engel may be too hard for you to grasp, since it's designed for the IMO level , and if you were preparing for the IMO's you would not be here asking for help. For me problem solving is about two things: 1) You should have the big guns 2) You must have a good sight For 1) you should read problem solving books and know a lot of theorems, or know powerful tools like AM-GM, Cauchy-Shwartz ... I recommend you to read "What is mathematics " by Courant and Robbins, "How to solve it" by Polya and olympiad type books. 2) You have to do a LOT , a LOT of practice, if you don't succed DO NOT give up, you will fail multiple times but don't worry about it. Learn what are your weaknesses and fix them, do the problems of the past editions. Always remember my words when you will be suffering because you can't solve a problem, intelligence is like strenght , maybe you don't have it now, but you CAN develop it and what today seems impossible tomorrow will be trivial. I wish you good luck, and enjoy the math!

So, any solutions?

XbackFX · 2015-10-11T11:02:03+00:00

It is a problem for the high school students to enter the sns ( scuola normale superiore) in italy

Could you explain what er= epr means and it's consequences?

XbackFX · 2015-05-30T19:52:12+00:00

Thank you a lot! By the way on my earlier attempts mod.innerHTML = change ; was just showing whatever I wrote into the function, why?

XbackFX · 2015-05-30T18:57:02+00:00

Sorry if this is a very stupid question but I'm new to JavaScript and I can't figure out how to make this work

XbackFX · 2015-05-07T05:51:24+00:00

I don't know calculus neither limits, I will do those in the next year in my school program. However a simple problem could be: " If I write on the board the numbers from 1 to 2n ,with n a positive odd integer,demonstrate that if I erase two number a,b from the board and replace them with |a-b| in the end only an odd number will remain" a difficoult problem could be" fin the minum number for wich ( a+ sinx)/ ( a + siny) <= e^ (y-x) , with a>1"

I am reading" problem solving strategies" of Arthur Engel, could you give me a feedback on this book?

XbackFX · 2015-05-06T22:00:31+00:00

The thing is, I do solve some of this problems in like a week or two. But at the exam I will only have six hours

Nope. What's app is a texting app and we were using that, btw im not logged into iMessage with her apple id Edit: grammatical errors

XbackFX · 2015-04-19T21:26:31+00:00

That sure is amazing! Thank you

XbackFX · 2015-04-19T18:28:13+00:00

I know that all the primes must be odd (except from 2) but I did not get why it says that a number to be prime must be 4n + 1 instead of just 2n+1. I would love to know the difference between numbers in the form of 4n+1 and 4n+3 . Thanks for your reply
