intensity and frequency are totally different properties. The frequency is the number of waves per second, and that is how we classify the EM Spectrum - high frequency is Gamma ---> Radio waves have a low frequency. Intensity refers to the amount of photons something emits. Intensity...

im pretty sure 'related rates' is 3Unit work, not 2 unit...

a third? im sure the website would have some stats

pedestrian 3U question

no worries, these types of questions are known as pH of solution questions, and if im not mistaken it was in a MC Q in last years HSC

work out how many moles of OH- there are how many moles of H+ there are, and hence which one is in excess, and by how much [this is because k+ and no3- just dissolve in water) then u know volume = 25+20 = 45 mL = .045L then apply the pH/pOH formula so for OH-: n=cV =...

true, at uni we've been taught to use a simple conclusion like "Hence the statement is true for all n≥0 by the principle of mathematical induction" Having said that, i find that at year 12 3Unit level, having the conclusion i wrote above helps students grasp what it is they are doing (proving...

I was taught: Therefore we have shown if the statement is true for n=k, it is also true for n=k+1. As it is true for n=1, it is hence true for n=2, hence n=3, n=4, etc. i.e. it is true for all positive integral values of n, by the principle of Mathematical Induction.

Disadvantage: No calculus If your planning on doing commerce/science/enineering at uni, ud want at least a basic background in calculus, which 2U gives you...

Exam results will be on estudent in about a month i think. Dont know about assessments during semester - maybe through blackboard?

True, ATAR sounds gay do we pronounce it 'aye-tar' or (like we did for UAI ) 'Aye Tee Aye Are' lol

you will need to do uni maths if your doing actuarial studies/finance/accounting

more than a rumour mate, its official. the 100UAIer's of 08 are the last of a dying breed...

n=5, p=3

http://www.uac.edu.au/documents/atar/ATAR-Conversion-Table.pdf It seems anyone who got 99.75 UAI or above pre-2009 has a 'slight' advantage, wherease those who receieved a UAI 99.15 or less has a slight 'disadvantage' in that between those values, UAI = ATAR 99.75 and above the number...

scalaing doesnt change at all does it? just instead of 100, top x students will get 99.95, etc..

graph them also graph cos(acosx) and tan(atanx) and acso(cosx) and atan(tanx) :)

yeh chemistry has no 'maths' in the senes of calculus or anything like that. They give you formulas (not a lot of them),a dn its just substituting values in

I dont understand what the problem is? U learn how to draw lews dot diagrams in year 11, and you have to do it in the ozone chapter in Topic 3 of the HSC course - so yes u need to know that. Also, in that same ozone chapter of topic 3, u are required to learn what a co-ordinate covalent...

H has one electron H+ does NOT (its an ion...) thats why when we talk about 'proton donors' we talk about H+ - they are just a proton, with no electron (at least the isotope Hydrogen-1) Also, OH- has 3 lone pairs okay see it in pictures...
