I'm hoping for a Series/Induction/Polynomials in Q16 with less Mechanics. I heard Mechanics is slowly making it's way out of the course so maybe even less Mechanics? (I hope that's true)

Re: HSC 2013 4U Marathon Yep, sorry. Read the EDIT please

Re: HSC 2013 4U Marathon New question by me. EDIT: Deduce that Z1,Z3 and Z3 are Cyclic with the centre as k. Sorry about that

Re: HSC 2013 4U Marathon I guess I'll have to continue it for two roots, three roots.... rather than extrapolation?

Re: HSC 2013 4U Marathon I'm not sure if this is correct but I guess i found one polynomial solution? EDIT: (there should be a plus minus sign after the quadratic is solved) When I solved the quadratic, I should get two solutions so the 2nd polynomial would be p(x) = (-1)^(2n) x^n (x-1)^n...

Re: HSC 2013 2U Marathon If I was marking this, I would give it full marks. If you want to 'improve' it, I guess you should focus more on the fact that perfect squares cannot have a difference of 1 as that is the heart of the solution. Well done.

Re: HSC 2013 2U Marathon Yes, I have written full papers (2U,3U,4U) that I keep as a way to explore my interest for mathematics :)

I agree. Btw, I could say the same to you. SNSD XD

Re: HSC 2013 2U Marathon Another Q by me ^.^

Re: HSC 2013 2U Marathon

I must admit though... I know alot of students who instead of studying, constantly worry about the method BOS moderates marks etc. and eventually end up predicting 30+ scenarios of marks, satisfying themselves and then don't even study at all.

Re: HSC 2013 4U Marathon EDIT: Was an error in the image.

Im thinking around the same as last years but I guess for different texts, it has different variations.

Re: HSC 2013 2U Marathon First 2U Q I made. EDIT: The Q means Tangent at that x-value for any clarification issues.
