Which latex generator did you use? The one you used looks much better than http://www.codecogs.com/latex/eqneditor.phpYeh man!
 has roots \alpha_1, \alpha_2, ..., \alpha_n \therefore P(x) = (x - \alpha_1)(x - \alpha_2)\dots(x - \alpha_n) \\ \\$ $ Log both sides and applying the useful rule: log_e ab = log_e a + log_e b\\ \\ ln(P(x)) = ln(x-\alpha_1) + \dots +ln(x-\alpha_n) \\ \\ $ $Differentiating both sides with respect to x \\ \\ \therefore \frac{P'(x)}{P(x)} = \frac{1}{x-\alpha_1} + \frac{1}{x-\alpha_2} +\dots +\frac{1}{x-\alpha_n} \\ \\$ $ Times both sides by P(x) and zu end up with ze answer!)
Is this actually a 4U question?Let m and n be the roots of the equation. Show that b and c are the roots of the equation
.
For the second one, consider what you did for the RHS of your expression, but do that for I insteadI think the first part should be:
(i) Letand
(ii) I got this:don't know if it helps. Any way, how do you do (ii)?
oh shit, accidentally deleted the post
See how you can bold text using the [.B] amd [./B] (without the dots), like this: bold (to see the tags quote this post)oh shit, accidentally deleted the post
Can you please tell me how you do your latex? The website I use doesn't allow spacing...
Ok, thank youSee how you can bold text using the [.B] amd [./B] (without the dots), like this: bold (to see the tags quote this post)
So for latex, use [.tex] and [./tex] (without the dots), like this:
There is a short guide on how to use it

I have done this question before but a, b, c and d must all be positive real numbers so shouldn't you write that in the question?.
YesI should of put that in the question, good work anyway. I wil leave the Conics question to someone else who has learnt all of itI have done this question before but a, b, c and d must all be positive real numbers so shouldn't you write that in the question?.
^{2}\geq 0 \Rightarrow a+b-2\sqrt{ab} \geq 0 \therefore \frac{a+b}{2}\geq \sqrt{ab})
Question: Have you and RealiseNothing done the whole 4u syllabus already? lol
I have kind of done all 4U topics but completing the course doesn't mean shit so now I will just keep doing past papers and harder questions (and pay more attention to English, UMAT and science).
I have already completed the 3U course which is why I am able to do most of the Harder 3U questions on here, but in terms of the 4U syllabus I only know what I have been taught in class + Integration
