Q29 Answer: Ok so I cheated haha. Why would you do it in first principle seriously...

Solution to Q22: Q23: Prove that e^(ln x) = x

Yeah I used about 58 booklets. A nice even number I think. Satisfied with that amount.

I did shit! I only wrote 154 pages!

I think I did a lot better than trial. At least this time I completed the exam. I thought the comprehension question repeated themselves a bit but they were straightforward. The speech to Yr 7's was a bit suss but I managed to write 1.5 pages on it so I'm fairly satisfied. I did the...

Seem like you go to a pretty small school. Do you know what that school is ranked?

Very high 90's.

Hey thanks for the replies. It's a shame that these forums aren't more active. I'm pretty sure that we do have to talk about all types of journeys. I don't think we have to focus on one. That said I am not sure if we need to address all of them :/. For the techniques so far I have about 2 to...

I'm doing this text too. In my essay I talk about the imaginative journey as each of the characters respond to the prospect of a physical journey. Since it's not very easy to talk about the journey in this particular text I mention lots of techniques. I describe the characters reactions to the...

English advance and standard get to focus on just one type of journey (physical/inner/imaginative). Is that the case for use ESL students or do we have to discuss all of these? Also how much should you write about techniques? Would 2 techniques per text be enough? Is it important to...

I don't quite understand the logic behind that second last line. Other than that you're graph looks perfect. Finnaly someone with a solution that looks correct hehehe... Thanks for the help by the way, appreciate it.

Wrong. Je mange du caca. Knobhead!

I don't think summaries for maths is useless at all. I find writing summaries very helpful. It's good revision.

Differentiation of cos2t y =cos2t y = (cos t)2 y' = 2(cos t) . (-sin t) y' = -2sintcost

In ASCII. Wow, that's pretty leet. Very nice.

I'm still not confident with those graphs and I am still unsure that the solution which you provided is correct. I did it again and this is what I found: y = tan-1(tanx) Consider y = tan-1A The range is always -PI/2 < y < PI/2. So we have determined that the range of the original...

So the initial graph posted on the first page was wrong? Any one brave enough to post a sketch of this thing?

Ah yes. I realised that since it's just a constant we could just have it on one side. I guess it saves a bit of time, I was just trying to make it clear :P.

I'd give it a go if "relitive" was spelt correctly.

Cheers. I think that I finally figured it out. Can you just confirm that the following is the correct working for such a question: y=tan-1(tanx) tany=tanx y=x Taking into account that the range of y=tan-1A is -PI/2 < y < PI/2 Since we have no restriction on the domain of tanx, we sub...
