One question that i have is why is the vertical tangent always stated, even it isnt really relevant to question. Also how would we formalise this solution?

How to graph this from scratch? y=x(3+sqrtx) Do we have to know the general form of it?

What did you do there?

o thx goodness... its math in focus... lolz +rep uncle EDIT: You must spread some Reputation around before giving it to Uncle again.

yea wth... if study freak cant solve it then no one can...

The root of the equation e^x-x^3 = 0 lies between x=-1 amd x=0. Use newton's method once to find an approximation to the root correct to 2 decimla places. This question has me perplexed. Using x=-0.5, and e^x-3x^2 = f'(x) i get a= -0.5 - (f(-0.5)/f'(-0.5)) = 4... something Help?

Which book is this from?

Wait... wats the problem?

Find two integers between which the roots of ln(x+3) = x-1 lies. How is this done mathematically?

There is an actuall digital copy but um... its new so i dunno if anyone has posted it up yet.

hahaha +rep!

The piratebay is great for mainstream stuff. Demonoid too is back and its got some very rare files. Not that i use it.

Well power was always subjective...

Those brain washed rice farmers makes up 1/5th of the world. So China contorls 1/5th of the world. Pretty good rite?

Freedom is good to the point of harming society. That is the rasonale behind laws, protecting society. Internet censoring too will benefit society. It will only censor those breaking laws. If however, our oppostion are against actions that are currently illegal, i.e. ethuanasia, abortion...

It wouldnt be 95% of all porn websites... they can never achieve such a ban, unelss utilising a "white list". And last time i checked, euthanasia and abortion material were both illegal? Just like child porn and rape. So why shouldnt they be blocked?

Hmm, the syllabus always talk about phsical and chemical properties of ethanol in terms of solubility. And it dosent really focus on physical and chemical properties used to replace fossil fuel, but rather its renewability, abundance and its ability to be derived from biomass. However, that...

Is someone picking you up on the other side? If so, your journey should be swift and easy.

I have this question. Find the modolus and argument of each of hte compelx no. z1=2i and z2= 1 + sqrt3i. Mark on an argand diagram the points P,Q,R and S representing z1, z2, z1+z2, and z1-z2 respectively. Deduce the exact values of arg(z1+z2) and arg(z1-z2) For this question, the solutions...

ahh thxs guys.
