who else is doing the independent prelim paper for their yearlies, cause i am. i was wondering if anyone can give me a link to past papers for the three sciences thanks in advance.

i cant seem to be able to do this question, like i dont understand the scenario. Amy rides a toboggan down a steep snowcovered slope. Starting from rest, Amy reaches a speed of 12 m s−1 as she passes her brother, who is standing 19 m further down the slope from her starting position. Assume that...

hey guys, i am just attempting a circle geometry question which i just cant seem to get the sketch for, i think it might be wrong unless i am retarded or something. here goes. AB is a chord of a circle, center O. the circle with AO as the diameter cuts AB at c.prove that C is the midpoint of AB.

hey guys i am just having troubles with a polynomials question. ok here goes if one root of the equation x^3-bx^2+cx-d=0 is equal to the product of the other two, show that (c+d)^2=d(b+1)^2 thanks in advance.

i have a physics portfolio to do:mad:, and one of the questions asks you to derive Kepler's third law of periods. i cant seem to find any resources that give a derivation that i can understand even slightly. any help would be greatly appreciated. r^3/T^2=GM/4pi^2

what are the best type of past papers to study for the prelim yearly and if anyone has some may they prease post them up as i want to start doing past papers. thanks

hey guys. we have just started plane geometry and circle geometry and to be honest it is my weakest point. i just cant seem to be able to prove things. so do you have any tips or resources which you could give me in order to help me. thanks in advance

a car traveling east at 20m/s moves around a curve at constant speed until it is traveling south at the same speed. if the car takes 5s calculate the centripetal acceleration. i am a bit confused as to how to find the radius do we find the distance then multiply it by 4. and form a equation...

sorry guys but i need help with another question. p(x) is a odd polynomial of degree 3. it has (x+4) as a factor and when divided by (x-3) the remainder is 21. find p(x). i don't even know where to start for this question.

p of x=x^3-8x^2+9x+18 is divisible by (x-3) and (2x+1). by considering the leading term and the constant term, express the polynomial in terms of three linear factors. and hence solve p(X) is less that or equal to 0. i know how to do the question since i got the one before it but for some...

i was just wondering if there are any worked solutions to textbooks such as Cambridge and Fitzpatrick. if so could you upload all you have. thanks allot i am in desperate need of them

im just doing my homework and i just cant seem to do this question it is doing my head in. 2sinx-2cosx=root6 for x between 0 and 360 thaxs

when preparing for a test is there a specific order of the books that u use for questions, or do u just do random questions from any textbook.

im gunna go out and by myself a maths textbook tomoz and was wondering what to get i already got cambridge. and if i was to by fitzpatrick should i get the extension one or advanced one( which one is more relevant form prelim)

we just had the half yearlies for maths. now the test was so surprisingly hard and since my teacher is an author didn't help either. i think i might've came 2nd with a approx mark of 22/45 what does this mean.

hello i was wondering how do we work out the school rankings if we know the results and what they are out of. for example i got 18/23 for first assessment and then 37/50 and the other person got 21/23 and 31/50. so who get first and who gets second. forgot to add they are both worth 20%.

hello, i am in prelim but i just wanted to know where i satnd in terms of atar according to my ranks. eng adv-2/70 maths adv-4/70 maths ext-5/25 chem-2/40 bio-4/45 and my school rank is shit like 350 i think

i have reached the end of my past papers and there is one more question which i just cant seem to get. i kinda know how to do it but yeah. find the equation of any line which makes an acute angle of 15 degrees with 2x-2y+7=0.

how would u sketch y=tan(x-45) thx in advance

i was trying to solve this question when i just couldn't find how. without solving the polynomial X^3-X^2-X+1=0 WITH ROOTS A,B AND C. find the value of A^3+B^3+C^3
