just need to put N in =)

This one follows the t formula.. i made a mistake with my sign, you can use 60 but not -60.. sorry about that. you know sin x/2 = 2t/1+t^2 and cos x/2 = 1-t^2/ 1+t^2 right ?? sub them in you get 1-t^2/1+t^2 + 2root3 t / 1+t^2 = 2 simpify you get ( that is remove deno ) 1-t^2 +2root3 t =...

u naa i used transformation method... it is used to solve any trig equation in the form of acosx (+ - ) b sin x = C or bsinx (+-) a cos x = C if you want me to use the t crap, ill post it up... look in your text book or notes for transformation, or do you want me to explain to you how...

use transformation method, its the best one out, or if your good at theta/2 method use it. ill give u the method. R= square root of 3+1 = 4 = 2 tan a = root of 3 over 1 = 60 = pi/3 therefore 2cos(x-60) = 2 divide by 2 and then take cos of 1 = 0 so x - 60 = 0 and also 360 therefore x...

one of the qusetion said .. use the results sin^2 x = 1/2( 1+ cos2x) to show that sin^4 (x) = something i forget I knew what i was doing i wrote my answer like this WHEN you expand cos( 2x + 2x ) you get sin^4 (x) = something never ever do this guys =)

I haven't even done those topics, so i woudn't have a clue about them... plus read my question it wasn't even answerin the question. ill say thanks but no thanks, i think he/she wanted to show off.. sorry but thats the way i see it. ohh well, what the heck... and sildey if you think 1st with...

ok i did that poly question, conics they were pretty straight forward i havn't done the rest yet... why not post some on these topics. Integration, conics, graphs,complex numbers !!!

Hi, I always faced with that word " Scholorships " and I think this will make my life abit easier if I had it. Does anyone know where I can get one or apply for one. I need HELP eg ( financially, etc etc you name it ) I'm getting 5-10 points/mark extra for my UAI already, but I want to get a...

Hi, I was just wonderin where can I find Random ( hard, I mean really hard ) TOPIC BY TOPIC Ext 2 / Ext 1 Books/ papers etc etc on the net or shops. I currently have Fitzpatrick ( for babies ) and Cambridge ( ?? ).. I find these two books not good enough some how, I dont know why, like i can...

Re: 回复: Trig!!!!! looks like people already of done it.. think logic not maths.

yeahh ext 2 4 life. its full of shit.. sorry but i find the chapters in 4unit pointless. they are not really hard ( cambridge ) ???? Complex did it in my head, graphs just have to look at it, conics ( wtf ? ) ./.. same bullshit from locus of a parabola.. integration double bull crap... they...

i have the shittest timetable out :@ freakin 1st day business studies then followed by stupid 2 days english and then next week ext 2 maths > economics > ext 1 maths.. I finish my hsc exam all in the 2nd week :@ double pissed.

Try using Train Trap. Always works like a charm. Train trap is when you try to get out of the freaking train, but its too packed and people wont move out of your freakin way.

4unit 91% 1st =D 3unit 91% 1st =D Economics ( NOT MARKED YET LOL ) I know I'm coming second with what ever mark Business Studies 71% 3rd << Screwd up hard in the response ( didn't even answer the bloody question ) Got High marks for both multiple and short answers. English 83% ( Not ranked yet...

|A| ≤ |B| and |B| ≤ |C| then |A| ≤ |C| You said if A is less than or equal to B and if B is less than or equal to C then A must be less than or equal to C because if you say B = C then A less than or equal to C .. What kind of maths questoin is this... ?

ohh ok so it doesn't apply there.. no high powers i see i see thanks. cuz this question is pissin me off.. how on earth do you learn table of indefinite integrals.. there are soo many, i basically have to look at the table and see where i have to use it... ?? is this the only way ??? I'm...

Hi, I just started Integration today, and was wonderin with this rule.. it goes like this S f ' (x) / f (x) dx = ln | f(x) | right ? therefore when u apply this here S sec^3 (x) tan (x) dx = 1/cos^3 (x) x sin(x) / cos(x) >> sin(x) / cos^4 (x) right ??? therefore f(x)= cos (x) and f '...
