No problemo. :) I_F

Let angle SQP be x. Angle SRP = x (equal angles stand on equal chords) Angle SRP also stands on chord BP. Therefore Angle BAP = x (equal angles stand on equal chords) Therefore Angle BAP = Angle SQP. But Angle BAP corresponds to Angle SQP. Therefore SQ // BA (corresponding...

It may be a bit late now, but schools usually keep their past papers and some schools have them going back for several years. If possible, see your teachers/check into school and see what you can find. I_F

Extension English = more work, more texts to read, more time spent doing English. Doing Advanced English is no basis for also doing Ext. You do Extension because you LIKE English and you'll put the effort in. You don't do it for brownie points because it's simply too much extra work to...

Try using Tinyurl. Enter the long url and Tiny will shorten it right down. Then try the embed. :) I_F

That probability of an event that will always happen is 1. Similarily, the probability of an event will never happen is 0. Thus, you subtract from 1 to find your probability. 365P2 the number of permutations, and is a shorthand way of writing: n!/(n-r)! Where n! is the total amount of...

Seems as though 90% of shows follow a basic formula like that. If people like the formula, no particular reason to vary it too much episode to episode, though season to season changes are nice. I_F

You usually ignore the leap year, if I recall correctly. To factor it in, you'd have to multiply in the chance that someone is born in a leap year on February 29 - 1/4 x 1/366, I think. NNot too sure on that one. 365P2 is permutation notation - 365 total events, and you want the probability...

That second cartoon is a hoot! Teehee, the only TV I watch now is on Wednesday nights. Woo for House. :p I_F

That's a nice expansion .ben, but I think the (2^k+1) is actually 2^(k+1), like word. said, which expands out into 2^k.2^1, I think. Ah well. We tried, Dreamerish. at least we can say that. Thanks for pointing that out, word. I_F

2 to the power of 0 = 1. cos^1 θ = cos θ Using your brackets: sin (2^(n+1)θ)/2^(n+1)sinθ = sin (2^1.θ) / 2^1.sin θ = sin 2θ / 2 sin θ = 2 sinθcosθ/ 2 sin θ = cos θ I don't see any problem. Where is it? I_F

We had them in about 4 questions. Show this with electron dot diagrams. Using electron dot diagrams, represent this. Bah. I_F

Dreamerish: I got up to about there too and gave up. I tried rearranging the exponents, but that didn't help. Is there some trig rule you can use or is it just stupid indexes? :p I_F

For induction: 1. Prove true for lowest value of n (0) cos2^0 θ = cos θ sin (2^0+1 θ)/2^0+1 sinθ = sin (2θ)/2 sinθ = 2 sinθcosθ/2sinθ = cos θ = LHS 2. Assume true for some value n = k 3. Prove true for n = k + 1 (this section gets a bit yukky, anyone else want to...

I don't remember a question on Global Aid for our SC, kadill. But then again, I don't remember much of it at all... Exams and trials first week back? Ouchie... what a way to ruin a holiday :( I_F

Physics: 88 (66/75, 1/12) Chemistry (teacher quote): If only you knew your Lewis electron dots, you would have had 100%! Stupid electron dot diagrams. :p I_F

Can you tell me what the Review questions look like, i.e. the title on each page, the format, etc. Then I can confirm it and scan the right one. :) I_F

Also make sure that each computer on the network has the same workgroup (Right click on My Computer, Computer Name tab). If one computer has a different one, it can throw everything off. I_F

"Blue cover with diagonal lines" - that sounds like Maths in Focus, by Margaret Grove. I've got the 3 unit books 1 and 2, which are basically the equivalent 2 unit books except with more stuff. The only thing is, they don't have a big review section at the back of the textbook - just revision...

Crap on for a while about how we sent billions to South East Asia, Iraq, etc. Oh, and don't get too bothered about the SC. It counts for nothing if you move on to Year 11 and 12, and Geography is the equal most useless section. I_F
