Current Year 12 Thread Mark II (2013-2014)

Hmm... My summer is about 2 months long. Not sure what's on the FP modules, but I've done quite a lot of complex numbers, proof by induction, Maclaurin and Taylor series I'll be doing next year. M1 is pretty straightforward and I know most of it, so M2 and M3 - when you say under 2 months, how much of those 2 months did you spend learning them?

Depends on what board you do. There is stuff like matrices (inverses, transformations, orthogonality, eigenvalues and eigenvectors, etc.), polar coordinates, lots of trig integration, reduction methods, groups, de Moivres, numerical methods, first and second order DEs, vectors (lines, planes, cross products, etc), stuff like that.

Probably 15 hours a week.

Matrices isn't on the syllabus any more, but I have sort of used them when dealing with vectors.
Orthogonality - does this have much to do with vectors? I've covered vectors, lines and planes with cross products etc.]
Never even heard of eigen values..
Polar coordinates - done
Trig integration - I'll be doing that next year
Reduction - row reducing? I've kind of done it (using matrices when solving plane problems)
Groups - I don't think we do...
1st and 2nd order DEs - I'll be doing that next year

Hmm, I think it may be worthwhile to learn M2, M3 and some FP modules then. 15 hours a week isn't too bad over a summer

Orthogonality. Sort of.

Eigenvalues/vectors aren't that bad, give them a google.

Reduction methods are a way of integrating functions that require lots of integrating by parts quickly.

Yeah, I am a quick learner though

So it should be easier to finish FP1, and 2 applied modules (E.G. S2 and D1) in under 2 months? I guess I'll do that over summer and then depending on how I find it, do the A2 stuff as well to go through during the second year.

I would say I'm ok, scoring 85% on C1, C2, S1.
Only got an A at gcse though.
It's just when applying to Uni, they'll see that I would be doing further maths AS+A2 in a year, even though I would only be doing 2 subjects alongside it instead of 3.

Do any of you know how ocr work their ums, I mean aqa has a converter for grade boundaries on pp, but ocr has a stupid PDF thing, which only says for particular grades! I was wondering what kind of score you'd need for full ums in exams, because for aqa bio I always check what ums I would've got in the pp I do!

The gaps between 10% boundaries are almost always the same.

For ums though?!

Yeah.

Out of interest, can you do this question? I'm certain that if nobody told me how to do it, I never would have done it.

Use the fact that $\cosh{ix}=\cos{z}$ (which that formula shows) and solve it like you would any hyperbolic. You can use the standard arccosh log formula or work it out yourself.

Haven't been taught about cosh, or its uses but I know they have something to do with catenary curves. Can you see any other ways to do it?

Yeah. Just solve the disguised quadratic in $\: e^{ix}$.

Wow, nothing slips past you xD
When the teacher at maths support told me about the disguised quadratic I was just like omg wait what ._.

Quadratics, quadratics everywhere.

Does anyone else find unit 2 physics on ocr really tedious

I think it's alright tbh, I find the electricity bit easy and waves Is alright. However we haven't light yet

It's not hard just dull, I like mechanics, but unit 2 is my least favourite unit in my least favourite subject! I adore chem though
