I'm not too concerned. My trial combined is only worth 25%.

Rather than thinking of it as 12 speeches, I'm focussing on a few to know in depth, then the rest with a small knowledge. That way you don't need to learn so many quotes.

At least we've got some 2 weeks of no tests beforehand.

Whoa, you're good. Seems to have cleared it up for me!! As for the rant, I know what you mean. But I think its better to at least understand the workings of the babble you are required to reproduce in the HSC.

Well I'm not quite sure what you mean Skunk, but here's a guess. Each of the curves on the graph corresponds to a specific temperature. As far as I know, the peak of the graph represents the dominant frequency being radiated (ie. the most photons of that frequency), but all the quantised...

Man, your class is wasting its time for continuers. I can't see the point of making you do essays when you aren't expected to reproduce that in a test. As for extension, you only have to do a 'mini-essay'.

Dap, I had exactly the same problem, as almost all texts skimp over that explanation. After much soul-searching and rereading of numerous sources, I think I have the answer. The problem with quantum physics is that everything is based on probability. As the atoms in the black body cavity are...

It seems you are limiting people to the subjects you yourself have selected.

thanks

"X-rays are created by accelerating electrons from a cathode across a potential difference of 60000V. Find: the energy of each electron (in eV and J)." Ok the answers respectively are 60000eV and 9.6x10^-15J My question is how can the voltage be the same amount as the electron charge...

Well it was the 30s, I think ppl were different then.

Same. Thanks for the comments.

It's true, I got full marks on my change essay because of that. I barely had an argument, just all the techniques down.

Ok, a grammar question. The verb, oderit, can be indicative or subjunctive. If it is indicative, is it classified as future, or future perfect tense? And if it is subjunctive, is it classified as present, or perfect tense? Does this follow for memini and coepi, even though coepi is...

1. sinx+cosx=1 (squaring both sides) sin^2x+2sinxcosx+cos^2x=1 (sin^2x+cos^2x=1) 2sinxcosx=0 sin2x=0 (lets say the domain is 0<x<2pi) sinx=0 for 0<2x<4pi 2x=0, pi, 2pi, 3pi, 4pi. x=0, pi/2, pi, 3pi/2, 2pi, for 0<x<2pi however pi and 3pi/2 are not solutions, as they are negative...

I was wondering if any of the maths excel texts are worth getting? Its also so confusing the sheer number they have. :confused: I mean the textbook they gave me at school must be about 40 years old, is covering in scribbled crap and I even had to write my own contents page. It just makes me...

Don't get me started on logs...

Thanks. My texts are In Catilinam I, Aeneid IV and for extension The Boor (Horace) and Juvenal Satire III. Did you guys do any of these texts?

Thanks kini mini. And the csu website doesn't have motors and generators, grrr.

I'd rather not divulge such info yet.
