Q7
(i)
Using the relation, and since , we have the solution , as required.

(iii)
Consider the relation again:

Note and since , this can only hold if , as was to be shown.

Note and we have if AND .

(ii)
Again, from the relation:

Note

Also

So and since , this can only hold if , as required.

Setting in the LHS of (*) yields 0 so we can observe that:

or , as was to be shown.

By plugging , into the equations (1), (2) and (3) and attempting to solve, you end up with . Note also that as squares are non-negative. By plugging these into each of (1), (2) and (3), they all reduce to \boxed{x+y+z=0}[/latex], as required.

If you're looking for any other specific solutions, just mention it and I'm sure someone will be able to post one up.[/QUOTE]

A little knowledge of matrices and determinants organises this nicely....

Terrible. Whenever I did practice, i would usually get 4-6 fully done. I only got 1 in this. A combination of exhaustion (4 hours sleep - i couldn't sleep) and the fact that I had been doing exams for the past 2 weeks and hadn't practiced.

I really liked how you did the last bit. I don't know how you came up with equating areas though... is that something you've seen before or did you just think 'this is going to give me something simpler to differentiate'?

On a separate note, I'm certain I've seen Q4 before - but the only place I would've seen it is in Further Maths conics. Had anyone else seen the question before? There's no way I would've known the constant is 2 before doing the question otherwise...
yes...the standard way look like horrible algebra.....so i look around for something simple....and there it was right under my nose!!!!

I took the STEP 1 paper, and was wondering how many marks I would get for my partial solutions.
I think I solved 2 questions, but came very close to solving two others. i.e I did the easy initial parts and made some headway for the concluding part at the end. Will I be able to get 10+ marks for these - or should I be feeling lucky to get a 2 grade? Thanks

It depends on how much you have done of each question.

Which questions did you come close to - which parts did you do?
10. Roughly how many marks do you think one need to get a grade 2..

Does anyone know when the STEP grade boundaries will be released?

I've felt so restricted without internet access for so long! The paper was ok imo, q8 and q1 were the most approachable - and then from there i did about 4 more partial attempts of varying quality.

Agreeing with others that this paper was definitely harder than past ones, I thought q5 was a lot harder than what meets the eye.
