Sweet, those were not actually mod signs lol. They were [ .... ]

The second question was actually STEP 1. They have a lot of nice parabola questions which are easily accessible to people without C3/C4 knowledge :biggrin:

Yeah, I know. STEP I, Q2, 2005, right? :lol:

Did you just remember that on the spot? o.O

I'm guessing the first time you met that question, she made it a day you'd never forget?

Nah, I seem to remember all the questions I've done. :lol: Each STEP question has that distinct 'flavour' that sticks. If you want some more accessible STEP I questions, try these:

STEP I, 2012, Q4
STEP I, 2009, Q8

It's not on spec for the UK syllabus since you don't need to know how to turn it about any given angle.

However, the matrix (cos⁡θ−sin⁡θsin⁡θcos⁡θ)\begin{pmatrix} \cos \theta & -\sin \theta \\ \sin\theta & \cos\theta \end{pmatrix} is the matrix which rotates any matrix through an angle θ\theta about O. You'd use this matrix to find Q\mathbf{Q}.


Thanks :smile:

Lol, nope, I still have 3 modules to cover. I started taking A levels seriously and started working around early March.

If you are not in my position, I'd say you are doing fine.

how do you get 2n(n+1) ?
is there a rule i'm missing?
what do you do when you get n instead of r in brackets?

Consider when r=0 r = 0 then you have 2n+1 2n+1 but you also sum up 2n+1 2n+1 from r=1 r = 1 to n n , so you sum up (2n+1) (2n+1)(n+1) (n+1) I asked this question earlier and Zacken answered.

I've also answered this on the first couple of posts on this thread. :lol: Pretty popular question.

Oh yeah, I remember repping that, and it was a pretty popular question in my FM class last week. :biggrin: I don't recall seeing any questions of that type in the textbook and It's only been in an R paper.

So make sure that you work through the R papers (and the appropriate questions on the IAL papers).

Definitely, I'm going to do an IAL paper today in fact.

Leave out the question on each F1 paper about alpha and beta.

This was actually the only way my teacher has taught it, although I do know how to use other methods, so it should be fine.

Has taught what? Are you doing IAL or "ordinary" A level?
I thought the edexcel FP1 book teaches Alpha and Beta way to work out the quadratic equation when given two complex roots?
Or are you guys talking about something else
