just to make it more readable x). (1+sinx+icosx)/(1+sinx-icosx) = sinx + icosx DEDUCE that (1+sin pi/5 + icos pi/5)^5 + i(1 + sin pi/5 - i cos pi/5) = 0 I have to prove that LHS = RHS right, but am i allowed to divide the whole equation by (1 + sin pi/5 - i cos pi/5) so i get (sin pi/5...

My question states (1+sinx+icosx)/(1+sinx-icosx) = sinx + icosx DEDUCE that (1+sin pi/5 + icos pi/5)^5 + i(1 + sin pi/5 - i cos pi/5) = 0 I have to prove that LHS = RHS right, but am i allowed to divide the whole equation by (1 + sin pi/5 - i cos pi/5) so i get (sin pi/5 + icos pi/5)^5 +...

yeahh i just realised ><" i kept forgetting to square the imaginary component ><"

Excercise 2.2 if p is real and -2< p <2, show that the roots of the equation x^2 + px + 1 = 0 are non real complex numbers with a modulus of 1. Yes I've checked the worked solutions xP... doesn't seem to explain the 2nd part of the question..

i think the best thing to do is to understand why they work... visualise... :). or if that doesn't work... take a step down and accept xD....

I thought in a typical 3 mark induction question you'd usually get 1 mark for the initial process of the n = k+1 and simplifying another for substituting or using the assumption... and a 3rd mark for justifying the statement for n = k+1... so all 3 marks are allocated in part 3...? though u...

Could anyone send me a copy if its online..? Anyone willing to send a scan to me? ijuinenzan@hotmail.com is my email btw :). if your bothered to go that far... thanks!

lol has anyone ever thought about how people make up inductions... they must be pretty retardedly bored. xD.

Is there a correct, short generic way to conclude MI...? It seems my teachers are always picky on what you write as a conclusion in ur mi statements... ><"... whats a satisfying enough conclusion that most teachers will accept?

So a borderline band 6 getting an alligned mark of 90 would mean that subject gave you a scaled aggregate of 90? or is that not how it works?

Does the band system for alligned marks follow the same system as the SC one? ie 90-100 = Band 6 80-89 = Band 5 70-79 = Band 4 ect...?

Well the title states all, what exactly is a band? Is it the same as the school certificate where a post scaled mark of 90+ = band 6, 80-89 = band 5, 70-79 = band 4 and ect...? or is it a different system?

I missed 3 of the last 5 questions by 1 -.-"

i dont know, but all i know is heart of darkness was used to make shadow resist gear for mother sharaz in black temple >_>"

>_>" Lol. I did this question for my mate a while ago and i handed him the solution but now and he lost it... & I can't remember how to do it.. could someone post up the solution... noting Q is at (0,-ap^2) for simplification.

haha mines next week... xD i was gonna go as Kuran Kuname not that anyone knows who that is anyway xD... $150 for 4 events isnt that costy... xD thats like averaging $37 ea

Watch out for Question 7.

Theres also a pretty tricky method solving by general solutions for stuff like sin 9A = cos4A or similar stuff xD... but i can't be bothered going into that xD

x^2/3 - 2x^1/3 - 4 = 0 It literally said. Expand and simplify the values of x. >_>"

65% and 2nd in physics... wtf does ur school give you for physics exams lol.
