Hello wonderful people, Would you please be able to help me with this question: Eliminate the parameter and hence find the cartesian equation of the curve; x=1+2tanø and y=3secø-4 Thanks!

Why don't you have a creative by now? What did you do in trials?

Why do quite a few of you do essay first. That seems really illogical seeing as you've just had reading time to read the unseen texts and identify techniques in them, which you can now start answering in section 1. Instead of doing the essay after reading time, forgetting what the texts were and...

You can still get great marks with facebook. You just need to put in the time when it matters. If your on facebook the night before an assessment or exam wasting time there is something wrong, but if you use it as a reward for finishing a set of study notes or a past paper it could be...

Lol!!! I don't know what kind of teachers you're spending your time with....

Yes there is nothing stopping you doing whatever you want once you walk into that exam. There have been stories I have heard of people accidentally doing every option in the exam, effectively doing the whole paper. If you do this they just give you the mark of your best option and count that...

Hello?

Hey Guys, Does anyone have any good belonging related texts that either they used or knew someone who used it? Our core text is 'Romulus my Father' and I need to find some good related texts so I can write my essay. Cheers!:cake:

Dropping Extension English, really disliked it...

Our school finished prelim exams almost 3 weeks ago now....

Don't ever quote the question/statement. But I would use some key words from the question in your thesis and subsequent analysis. :)

^zing!! +1

I always use Papermate Profile, sooooo smooth!

~95 imo

haha....I'm on holidays anyway from today!!

Yeh we just started today and have learnt the first principle. How do I do it using the long way, because we haven't done differentiation properly yet :P

For y=x3 find dy/dx at x=1 I did this. How do I find the answer, because i probably did it wrong. dy/dx= lim 1-->c (13-c3)/1-c =lim 1-->c (1-c)(c2+c+1)/1-c =lim 1-->c c2+c+1 how do i get c????

(1/cot^2ø)+1=(1/cos^2ø) tan^2ø+1=sec^2ø (reciprocal functions) Therefore, sec^2ø=sec^2ø (trig identity: tan^2ø+1=sec^2ø)

1. (sec^2ø-1)cos^2ø=sin^2ø tan^2øcos^2ø=sin^2ø (using identity) tan^2ø=sin^2ø/cos^2ø (dividing by cos) therefore tan^2ø=tan^2ø

Hi Guys, i am almost there with this question but can't quite get the last step!!!:evilfire: Use mathematical induction to prove that for all positive integers n: 12+32+52+...+(2n-1)2= (1/3)n(2n-1)(2n+1) Thanks!
