# Mega A Level Maths Thread MK II watch

1. (Original post by reubenkinara)
In C3, for harmonic form is it okay if you already know how to compute R and alpha. Or do you have to do the whole thing by saying ?
I always show the method otherwise I'm concerned if I'd lose the method marks for it.

Yeah it also annoys me if I see a question that I can't do straight away so I tend to diverge from my current task to solve the question that has been asked, if I've got the ability and knowledge to that is I'd rather have the A level papers include some of the questions we ask on here instead of most of the repetitious questions that appear in the actual exams
I don't even bother trying them hence I was meant to disappear from the thread for a bit.

Proofs aren't that bad tbh! and that sounds more like jealousy than irrelvancy? (not a word don't quote me). Your in year 11, some of this stuff needs to be done by people in year 12 and 13 to become more open minded mathematically rather than following a tedious syllabus. You can class induction as fp1, and irrationality questions I have heard come up in c3 solomons or something like that?

Anyway I understand your point, but this thread feels a bit more approachable for people like myself getting into the whole the STEP thing if you understand why I mean.
Irrelevance*

It's not that I can't do them (I've never tried to actually). I guess I'm just stubborn in that I won't join in because I don't agree with it

It's not like I'm condemning it, I just... Yeah

I'm gonna get warned if I carry this on... and I have enough points so...

Something a level maths-y related...

I've decided not to go to any lengths with maths! Just gonna keep it simple... With FP1-3 M2-3 and S2

Haha very funny

Yeah, I think I get annoyed because I can't see the code on my phone and so can't be bothered attempting them tbh

Proofs just irritate me too!

It's probably because I never do them, and I feel crap when I see you guys do it.

Anyway... S1, seeing as my exams in over a week.

Any way in remembering all.those probabiliTy and Venn **** stuff?
HEY! I can't believe you get in trouble in your own thread for spamming :/
I enjoy proofs :P, I have an S1 notes/doc if you want it

Don't get me started

Ahah, my S1 is Edexcel S2 mostly. So it won't be the same, thanks though

What do you mean?

I say:

R^2 = ...
Alpha = tan^-1 b/a...

And then plug it in.

Emm I'm in year7 and I'm like really into maths I do yr 10and 11 work and sometimes even get 95 percent could you please tell me what should I be doing??

I see. Do you tend do draw diagrams for C4 vectors? I only do so when the Q is not straightforward whereas others draw them at every opportunity.

Sounds good, and similar to my choices as well, though I need to convince my teachers that I may perhaps want to do M3

I kinda feel obliged to post a problem to each post
how about some s2
Spoiler:

Given that for

Find the value of the constants a and b

That's what I do also but I don't want to lose any M1s this time around in C3. At the same time, I don't want to waste time!

No teachers can tell me what to do

what do you do for that? I feel so thick

I never draw diagrams for vector questions as I can't get the diagram straight in my head so it's pointless of drawing one that won't make any sense to me. But everyone else in my class always draws them, they don't get the correct answers though so it's really up to you

Sorry edited it! it was

I.e. the cumulative distribution function

Cumulative.d.f dx = P.d.f?

Not related to your thing, but?

I see. I find a rough sketch is extreemly useful in modelling vector questions with areas on geometric shapes.

You can find one the equations of a and b by doing this, but then you need to consider the area under a pdf (once you have it) being equal to 1. You can also find another equation by using the property of the cumulative distribution function, involving F(a number)=1

Ahh okays I have decent probability + venn thingies for edexcel s1

I just hack my way through all the working out instead and sometimes take about 15 minutes to get the final 3 marks, but I still get the correct answer so it's all good in my eyes

Each to there own I suppose. How's maths revision? I haven't managed to start yet but I'm not too worried. Are you in the zone, i.e averaging ?

Oh. You want me to do the question right, what is it again?
