Probably because you don't live up to their expectations :P

Re: MX2 2016 Integration Marathon ah yes 2010 question 8 was a 15 mark integration question? Also attempt anyone except paradoxica his insight is to good for such a crap question: \int \frac{(x+1)^4(x-1)^2\sqrt{x^4+x^2+1}}{(x^2+1)^2(x^6-1)} dx

4>2 \therefore $ If you do 4 unit you're smarter than if you do extension 2. $

I've spoken about laws of the universe and laws of God before. God will not help you if you don't satisfy the laws of the universe. For example I can't ask God to win the lottery (Assuming gambling is allowed in this example) if I don't buy a lottery ticket. It's just not the way God does...

Re: MX2 2016 Integration Marathon Sean be like "Now something easier" Turns out to be impossible with HSC knowledge...

Re: HSC 2016 3U Marathon Y= \sqrt{1+\sqrt{1+\sqrt{1+...}}} Y^2= 1 +Y Y^2 -Y -1 =0

Re: HSC 2016 3U Marathon Golden ratio shouldn't even be known by a good extension 2 student.

Re: HSC 2016 3U Marathon \phi = \sqrt{1+\sqrt{1+\sqrt{1+...}} \int{\sqrt{x+\sqrt{x+\sqrt{x+...}}}dx $ I learnt golden ratio from questions like this. $

Re: HSC 2016 3U Marathon I think people should take note that 2 \leq k \leq 366

Re: HSC 2016 3U Marathon $ Hint: Take note that $ \phi ^{2n} +\phi ^{-2n} = (1+\phi)^n + \frac{1}{(1+\phi) ^n} $ Use induction and double assumption. $

Re: Flop math question thread Why would I add another operation to the formula lol ? It's not something worthy of being memorised.

ahahhahahaahahahahahahahahahahah wot... I do not accept money for such services and have never been offered money :)

Re: Flop math question thread Okay so how you determine these is like this : $ If $ 0< \theta < \frac{\pi}{2} \sin{x} = \theta x= \sin ^{-1}(\theta) \pm 2 \pi k $ or (using ambiguity of sin in first and second quadrant ) $ x= \pi - \sin ^{-1}(\theta) \pm 2 \pi k

Re: Flop math question thread Its finding all values for a trig equation. Eg: \sin{(x)} = 0 x= \pm \pi k $ Where k is any integer $

Re: Flop math question thread Also when you're doing general solution make sure NOT to remember the formula and derive it yourself (takes 2 seconds).

Nop, this is basically the confessions forum for maths.

You the real MVP.

No there's no other way to answer this except through solubility rules as they describe if things can physically be separated.

\frac{5}{8} $ Isn't a recurring decimal though ? $

Also : “God is not a man, that He should lie, Nor a son of man, that He should repent. Has He said, and will He not do? Or has He spoken, and will He not make it good?" Numbers 23:19
