Yes, terrorists now basically includes anyone who endangers the lives of others through deliberate actions for self/personal gain or satisfaction

yea, i mostly just play classical. Chopin, Liszt and Mozart, not any modern songs, besides Richard Clayderman's / Paul de Senneville's pieces.

For metal conductors, resistance increases as temperature in increases. This is because the atomic structure of the conductor starts to vibrate erratically, disrupting the flow of electrons - hence an increase in resistivity. That is why superconductors (almost zero resistance) only operate...

Seriously, have you seen the junk that some people wear? ie. Basketball singlets and shorts.

I mean, seriously who cares? They adults, they make their own decisions. Its not uncommon for 20yr olds to marry rich 70 yr olds. Think of it this way, it means the girl was 2yrs old when the guy is 52. now thats wrong.

Do your research before hand making such stupid remarks. The first person to contract HIV was bitten by a species of Chimpanzee carrying the SIV virus, which mutated to the virus we know and fear today.

If i use partial fractions, it becomes quite messy, but i get 1/2sqrt(2)*[arctan(1/2sqrt(2)*(2x - sqrt(2)) + arctan(1/2sqrt(2)*(2x + sqrt(2)] enlighten me on this substitution...

Does anyone here play piano just for the fun of it? I played for a year in Yr 8, but stopped for 3 years. Somehow, my interest in piano got reignited and so i just learn various pieces by my self when I have the time. Anyone else here in the same circumstances? I have never taken a test...

They're the exact same thing, except you've been on a date beforehand.

that is exactly right. Metals' conductivity decreases as temperature increases, but for semi-conductors, resistance decreases as temperature increases.

Depending on what salts are used, they may have various risks associated with them. Lead salts are carcinogenic, silver salts will stain skin and clothes. Instead of saying don't drink metal salt solutions, write about effects of different ones.

pLuvia made a mistake in the calculation due to the incorrect integration result. The correct outcome should be: ln[x+sqrt(x2-1)] from {rt2 to 3} => ln[ 3+ sqrt(9 - 1)] - ln[rt2 + sqrt(2 - 1)] => ln[3 + sqrt(8)] - ln[rt2 + 1] => ln[3 + 2rt2] - ln[rt2 + 1] (log manipulation)...

Shouldn't =[ln|x-sqrt{x2-1}|]{rt2 to 3} actually be =[ln|x+sqrt{x2-1}|]{rt2 to 3} its supposed to me a "plus" after the first x? Unless i'm wrong...

its an ellipse with a semi-sphere of radius 1 cutout.

Yup absolutely correct. However it seems e^ix=cisx might have to be be proved using the power series beforehand. Anyone want to take a shot at the question 2?

Found the following questions quite interesting: 1. Find ii where i = root(-1) 2. The number a is randomly selected from the set {0,1,2,3,...,98,99}. The number b is selected from the same set. What is the probabilty that the number 3a+7b is an 16 digit number?

Its a good method, but its a shame that many schools will claim it cannot be used unless first proven first - which is a bummer if theres only 1 or 2 inflexion questions in the exam. I totally disagree with this policy which forbids the use of non-syllabus knowledge. For example, a difficult...

Think about it.... 0.99999....... = 0.88888...... + 0.11111... But 0.88888...... = 8/9 and 0.11111...... = 1/9 Therefore 0.99999..... = 8/9 + 1/9 Hence 0.9999..... = 1

Can someone please enlighten me on how to actually do this question: Q1. Find ∫(sinmax)/(cosnax) in terms of m, n, Cos(ax) and sin(ax) Help would be appreciated!

seriously, no offence, but that sounds really dodgy... Sure you're not 74?
