This is all pop-sci nonsense. Nothing like this will happen.

In the Ganesh's puzzle section on the forum.

Anyone use brilliant.org? There problems are entycing. I can't solve them half the time though xD Is that website a good test of mathematical skill?
I am on it.
It is not an estimate of your mathematical skill - nothing is, to be honest. "Skill" is not well defined. It does reflect your problem solving skills and knowledge in a specific area of math, though.
However, high school math proficiency isn't really enough to estimate your skill.

Elementary & Intermediate algebra are the basics.
#181 Re: Help Me ! » Suggest me a good book to study math and physic » 2014-06-25 02:35:39
You must start with Elementary & Intermediate Algebra and then do Precalculus and Geometry simultaneously. You can use Basic Mathematics at the start, end etc - it doesn't matter.

OK.
These probably shouldn't take you more than a few months, by the way. Afterwards, you should be prepared well enough for Spivak.
#183 Re: Dark Discussions at Cafe Infinity » Amateur » 2014-06-25 01:36:56
Yeah, as a supplement they are great.
#184 Re: Help Me ! » Suggest me a good book to study math and physic » 2014-06-25 01:35:22
It's great that you bought the textbooks, but why do you have two Precalculus books? Sullivan is enough.

I noticed old books seem to teach in a similar style but the new books I go through simplify everything and just show you the procedures. I can solve many of the problems but explaining why is new to me and I don't know why lol. Well there are some online resources like Kahnacademy & mathisfun to help me on parts if I get stuck. I like this book proves a lot from the ground up. It's just going to take me longer than expected. Also a lot at the back I haven't even covered before.
Khanacademy and the MathIsFun pages are suited for specific US (and other) curriculum, so they do not prove a lot either (don't get me wrong, I really like MathIsFun and it is good at it's purpose - helping students studying in the US/other countries, but it is not rigorous in a sense).
At present, there is no online source available that provides mathematics at the high school level in a rigorous sense. It's unfortunate, but true.
Don't worry about how long the difficult books will take you. If you enjoy it, the time will pass quickly and at the end you will gain much more satisfaction.

In regards to what you were told by people on another forum (someone told you that going through Hardy's book first will make Spivak significantly easier), it is not true. The problems in Spivak are difficult for me right now, even though I have gone way past Calculus. The problems posted in the other thread from a national Olympiad are still difficult, even though they only cover high school mathematics and I am way past that. The reason is that these problems require a deep understanding and ingenuity and will remain difficult for all mathematicians.
Since you finished your A-levels, you probably know some Calculus, which is basically all you need to get started with Spivak. If you really want, work through a less rigorous book like Stewart on the side.

Yeah, I got the email. I just missed it.
#188 Re: Help Me ! » With which book to start? » 2014-06-24 04:17:59
It is a good book, but I don't think it's worth going through it right now when there are many better books available.
#189 Re: Help Me ! » With which book to start? » 2014-06-24 00:35:19
Hardy is outdated.
Calculus is a part of pure mathematics.
There are a lot of better analysis books available.
#190 Re: This is Cool » nxnxn Rubik's Cube Theory » 2014-06-23 09:26:26
I don't think I got the email, unless you sent it in the past 5 hours.
#191 Re: Dark Discussions at Cafe Infinity » Amateur » 2014-06-23 06:13:25
Thanks Shivam for helping me realize how much of a novice I am.
That scared me.
It's not your fault, blame the government.
#192 Re: Help Me ! » With which book to start? » 2014-06-23 02:25:22
You don't need Hardy's book.
Go with Spivak. You can't really do both at once - Spivak's very difficult.
#193 Re: Dark Discussions at Cafe Infinity » Wish I don't have to go to school » 2014-06-20 12:17:07
Cover the whole syllabus and go in to depth so you have a chance to get A*'s for the science, maths, english, computer science. Those are the staple subjects for the future. nothing else matters.
English doesn't matter for universities in the UK, right? Don't they just look at three A levels?

I think he's in Malaysia, though.
#195 Re: Dark Discussions at Cafe Infinity » Wish I don't have to go to school » 2014-06-20 11:54:16
I think he wants to go to university.

I use Internet Explorer 11 and it has this feature that it remembers pages I have visited and, when I click for new IE page, it shows links to those pages. Useful for getting back to a frequently used page. So it remembers I've been on MIF.
So I log out; go to a new tab; there's the link to get back in; and it takes me there! ie. without having to log in again. Whoops.
EDIT: That's curious. I am unable to repeat this. I know I'm going senile, but I'm positive I did log out.
YET ANOTHER EDIT: It's just done it again. I have two tabs to MIF. The first says I'm logged out; the second is the one I'm using to make this edit. I'm not logged in.

It's because of the domain name. Like lets say you logout of http://www.mathisfunforum.com/ and you go to http://mathisfunforum.com/ you will still be loged in some goes with logining
Doesn't make sense. They are the same URL.

Good night.
I'll work on them now.
