Haha, Extension 2 is too cool for Dreamerish.

They brought in Vogler and to make it more interesting, and Three Stories does not follow this formula.

-180° < x < 180° simply means x lies between -180° and 180°. Yes, it has to do with ASTC. Your answer would normally be just 116° 42' if it was for x < 180°, but since it's extended to -180°, you need to take into account values for x which are below zero. From the previous post, you saw...

House cartoons. :D

They ask an ethanol question just about every year. I'm going to list all the disadvantages: It is extremely costly to distillate ethanol. It is 100% water-soluble, which means obtaining 100% ethanol is very difficult. Up to 11-13% of ethanol can be used in current cars without engine...

Correct! It's Hugh Laurie, possibly the most amazing old man I've seen.

Haha, ok then. :p cosx = 2 + √6 It can't be 2 + √6 because that does not lie between -1 and 1, and would have no solution for cosx. So the question is cosx = 2 - √6, for -180° < x < 180° cosx = -0.449489742 x = cos-1(-0.449489742) x = 116° 42', -116° 42'

Good stuff. ;) Thank you so much!

So... +/- means "times"? cosx = 2√6, -180° < x < 180° It comes up as an error because 2√6 does not lie between -1 and 1. Are you sure you copied the question correctly?

The Continuers course for language is usually not too difficult. I think you're confusing it with Background Speakers. If you can understand everyday-sayings and converse quite easily with your family, then you will probably find even Continuers quite easy. You could use this to your...

What is "+/"? It can't be "square root" because you have that as "sqrt". It might help if you wrote your question and scanned it, or just draw it up in paint. :)

Yes! That's it. :) You can skip questions 54 to 192 because I marked those at school. Thank you so much! :)

ROFL, you're absolutely right. Well spotted. :o

Don't you look at both sides? Usually it asks you to look at both disadvantages and advantages, and make a judgement. Your judgement doesn't matter a whole lot, as long as you have the ads and disads listed correctly.

I think you'll be fine with the neutral species equation and half-equations. :)

I can't stand Excel. They make me fall asleep. For everything, I do as many past papers as I can. Sometimes when I have trouble in a particular area I look in textbooks for some exercises. I also try to do the questions that other BoSers put up because they're usually somewhat challenging. :p...

For redox reactions, writing half equations is very very important. It is equally important to shove your states in. The oxidation half-equation is: Zn(s) → Zn2+(aq) + 2e- The reduction half-equation is: Cu2+(aq) + 2e- → Cu(s) The overall reaction is: CuSO4(aq) + Zn(s) → ZnSO4(aq) +...

I'm in the same boat as Tao. :p Perhaps an even worse one. I suck balls at Chinese Background. But then, Continuers is way too easy for me. So I've been stuck with newly-arrived-from-China kids for a couple of years. This is outside my 10 units, and I'm sure my results in it won't be...

No, you don't get debates. :p You would get questions similar (or identical, if I'm lucky) to: Assess the potential of ethanol as an alternative fuel. Evaluate the success of ethanol in replacing petrol as an alternative fuel. Assess the benefits and problems associated with the use...
