shafqat, any chance of you asnwering my other question??

edited out, its in the original post now..

i get bxcos@ + aysin@ = abecos@ how do u prove ecos@ = 1 (if u can prove this ii will b done in 1 step)

Conics Help Marathon <b>QUESTION 1:</b> P(acos@,bsin@) lies on the ellipse x²/a² + y²/b² = 1, where a > b > 0. The tanget to the ellipse at P passes through a focus of the hyperbola x²/a² - y²/b² = 1 with...

a(r^n-1)/(r-1) = 1500(1.14^15 - 1)/(0.14) = $65763.62 what ur doing is this 1500(1.14)(1.14^15 - 1)/(0.14) and is wrong because it says AT THE END OF EACH YEAR.. read the question properly..

A question like this that asks prove something equals 0 and you get it right means u would know at the exam time that you have got it right if u have proved it... so why did u ask how to do it, if u did it and u got the right answer... :confused:

just to be safe, know that u basicly cant quote (almost) any formula's.. In the hsc with those formula's which you can quote they usually have them already on the question, so you dont need to worry. Main formula's to learn is angle between 2 lines and quadratic equation.. Apart from...

find integral of cosec x dx using sub t= tan x/2 cheers

jeez do they want any more words in that question oooppsss i get 100bX(a - x)/a^2 everything else is good except for the 100... btw Q is an angle basicly i found that a = v^2sinQ.CosQ/5 and b = v^2sin^2Q/20 and played around with the formulae's i also made v^2 = 20b/sin^2Q

this means that X1 and X2 are both ae correct? i did it assuming that... and my y intercept is 0...... oh i just realized the midpoint of the 2 points should be the focus.. haha oops so yea it should be 0.. therefore there is no rise... and the gradient is 0 which is the same as the...

hey, I know alot of schools, mostly the selective ones don't require you to do sport in year 12, however my schools wants us to do it in the first 12 years. I know the board of studies does not require you to do sport for your hsc certificate... does anyone know any more info on this or can...

maybe if u can get ur english as good as ur maths a good uai will be very possible?? ;)

well, the hsc tests you looked out might not have had questions that directly have a log addition or something or something to do with e, but with integeration or app of calc in the physical world would have many logs in them everything in ur maths book can be tested in the ext 1 exam...

any mathemtically correct way of obtaining an answer is concidered correct in the HSC.... however, u cant just plug in certain formula's like physics ones for projectile... If you can show how to get the answer then thats fine... Just because your doing Q's in conics chapter doesnt matter...

uhh... currysause 99% in ur physics exam? whats going on there... i think some easy marking on the long answer questions... must have been a pretty physics exam aswell... to have more than 70 marks in it.. ( to have 1 mark off and only get 1% down)

Q3cii: I had no idea, i just wrote: to find the produce of the 2 and got full marks :s

hey, i dont really want to take my writing booklet apart, if u cant do any of the questions just post the ones u cant do and i will write a solution for em.. If i dont im sure Slide_Rule will......
