    Trignometry Formulae

    i'm glad the pdf's of use to many ~ but don't rely on memorising too much, as the key is still to understand then apply (by doing a variety of questions of course) :p

    should i do a physics bridging course?

    Get University Physics by Young & Freedman - finish the entire book, then you'd be done with first year and half of second yr phys HSC physics wouldn't help too much.

    measuring pH of identical concentrations of strong and weak acids

    Example 0.2M of HCl and 0.2M of CH3COOH would have different pH, as one is a strong acid (dissociates completely), the other is a weak acid (about 1% dissociation). Further suppose you have two acid solutions of equal volume, A and B, both of pH 2.53. You will not be able to conclude which...

    titration calculations

    Purpose of Titration What you are doing in a titration is you are trying to determine the concentration of an unknown acid (or base) using a base (or acid) of known concentration. A simple example would be like this: suppose you have NaOH of 0.1000 M concentration (this is your standard...

    Ka and pKa??

    Ka = acid equilibrium constant pKa = -log[Ka] If you happen to be doing industrial chemistry, then you would need to learn what they are, but they are not part of acidic environment i believe. METHOD I (the long way) Since you are given a weak acid, therefore it does not dissociate...

    Trignometry Formulae

    Yes, indeed trignometry appears to be a big problem amongst hsc maths students, and i'm glad this little sheet helped! ;) Good luck to you all '04ers! And always watch out for angles when you are doing trig, you don't want to use the wrong one...!!

    My throat's too full of carbohydrates to take in anything else :p and i'm sure no girls would want to sacrifice herself and another life for the pleasure of a man who raped her :D because the potential difference is so great that men do not have the opportunity to experience the 'joy' of...

    not discounting that :D potential is abstract but not unrealistic, selective school tests, uni entrance tests... all these things we had to sit for were there so that our potential to do things are being compared to others. Oh yes, it is gonna be slow, probably another 1000 years has to fly...

    Social restraint is no excuses, it's a FACT All I am saying is, it is true that guys appear more dominant in mathetimacs/science (in fact in a lot of other areas too), but whilst there would be evoluntionary factors, but that's not all, there are social factors as well. Having a world sample...

    I only admit I'm a feminist... hehe If all feminists are sexists then since merc is a feminist merc is a sexist Does the first premise stand? Not really, the original intention of feminism is working for gender equality (which I believe our society still lacks, more so in certain places...

    I really have no idea about what causes the difference in abilities... I always think it's half to do with evolution and half to do with social atmosphere. May be it is the typical bringing up of girls and boys... I don't think it's just in the genes :D And I disagree that gene mutation is...

    why am i sexist? :D What I mean is, proper education for girls only had a short life span (relatively). And i disagree that guys will always rule in maths and science, first of all, define "rule", if you are talking about scientific and mathematical achievements... i concede that currently it's...

    I think they just want to make sure that the top 3 unit student who didn't do 4u maths isn't disadvantaged (same thing for 2 unit students who didn't do 3u maths)... they may well be capable of doing 3 unit - you can be good at something that you don't like, and similarly be bad at something...
