i really dont know how much exactly but they are usually like $10 cheaper than other shops. he gave me fitzpatrick fo $70 when Dymock had for eighty something.
ok so soon we will be asked to choose our subjects for year 12, and i have kind of set my mind so as to do 4 unit, i have also been requested when i asked my teacher to do it. my question is so i want to get a head start should i buy all the extension two books now or like wait until we start...
can anyone help with question 24 in this paper, my test it tomorrow and im not sure if i have the right answer.

thankyou
there was a question in my test which i couldnt get. it provides you with a table 5 boxes in length and 4 boxes in height. the man started in the bottom left hand corner. it then said if the man can only travel north and east how many different ways can he take to get to top right hand corner.
idk the question since it was in my test. but in short terms as i just showed that one of the exterior angles of the quad was x. i then showed that the interior angle one right next to it 180-x since they are supp. then i said if it was a cyclic quad then the opp interior angle will be equal to...
,
no but mine was kinda like a proof by an assumption, i firstly assumed that it was a cycli quad and then found that they were supplementary concluded that it must be cyclic.
today in my extension test we had a circle geometry, quite a tough one which involved proving a quadilateral to be cyclic. well i didnt know how to do, so i decided to take a risk. and said if it was a cyclic quad then opps angles where supp and it worked then i said therfore it is cyclic, just...
i think i just might continueing doing questions before my test on monday as i seem to be learning new methods of removing paramaters in new situations.
yes, when i am doing the questions i am understanding the questions but tbh some questions i just cant seem to be able to remove the parameters until i see the method, then kind of see how it works and memorize it. it almost seems that this is what this topic is about.
in regards to parametric equations is it wise to remember the different methods for the elimination of the parameters in different situations or do you just figure out a way on the day of the test. thanks
p(2ap,ap^2) and q(2aq,aq^2) are variable points on the parabola x^2=4ay. so that angle pqr=90. the tangents at p and q meet at t. find the locus of t.
i know the process of doing these types of question i got up to
0=x(p-q)-a(p^2-q^2) and i know that you will end up getting that pq=something...
