and those α β questions which are usually easy had so many nasty numbers :angry:

Are you hoping to apply to Cambridge? If so have you thought about which college you would apply to?

Yeah I am hoping to apply for NatSci haha
Not really, but I think I might like smaller colleges :smile:

Bio or Physical?
I was going to recommend St John's, but that's a huge college!

Physical

Rich colleges should have a lot of advantages so it is attracting, but it is too massive for my liking possibly!

Use sum of arithmetic series formula!

You need to, for both your general solutions, find the smallest and largest solutions in the interval that they gave you. Then sum them and all the ones in between (by varying the 'n' in your solutions) with some clever manipulation and recognition of series. If you get stuck again, tell me how far you got and I'll help you from there. :smile:

I generally work pretty fast (never ran out of time in an exam), but it takes me ages to draw the graphs of rational functions and to find stationary points on them (only if the question asks), just wondering am I really slow, or is this the same for everyone?

It takes me a little longer than it probably should to draw the graphs carefully so they actually look right, finding stationary points by setting y = k takes a while but I wouldn't say it's disproportionate for the amount of marks given usually?

No, it should actually be quite quick? It's a pretty straightforward method so as long as you practise a few questions you should become quick at doing them.
Any reason why it takes you so long?

Working out all the asymptotes (not very long), where/if it crosses the horizontal asymptote, where it crosses y and x-axis, whether if the section between 2 asymptotes is upwards or downwards sloping, subbing y=k and then getting a quadratic then doing b^2-4ac=0 then subbing the answer back into te quadratic for the x-coordinate... Then I often check my answer on the graphics calculator! IMO this takes a bit of time but tbh I haven't spent much time practicing them so you're probably right!

Yup true, it's usually like 10 marks for the whole question and they split it up by like working out stationary points into different parts of the question (i), (ii) etc so i guess it's okay to spend a bit of time on it!

See if you just stick it into your graphical calculator first you don't need to do any of the working out what each section is doing (unless specifically asked!). Just find the asympotes, draw those on your paper, look at it on your graphical calculator and then copy the shape. Find any intercepts if applicable and you're done with the graph :smile:

Hey guys, I was wondering if you could help me on question 4 of the Jan 11 paper:http://filestore.aqa.org.uk/subjects/AQA-MFP1-W-QP-JAN11.PDF. I got the answer as x= 1/2n+1/8 pi or 1/2n+11/24 pi, but the mark scheme doesn't agree with my second solution and I have no idea where I went wrong. Thanks :smile:

So the pi coefficients come from your solutions for sin = -0.5, which are -pi/6 and -5pi/6 or alternatively (it says OE, or equivalent) 7pi/6 - I think 7pi/6 would give you your 11/24? (correct me if I'm wrong, I can't be bothered to get my calculator etc and check), which is equivalent to their answer as it's a multiple of pi/2 away - you've added on npi/2 to get to this one instead.

Ah, yes, thank you so much! I guess the OE would imply my answer is acceptable as well. Thanks so much :smile:

Yeah, pretty sure I did the same thing on this paper the other day! I'd imagine it's a very common answer because that's what you get from pi - initial solution :smile:

hello guys, I'm thinking of doing FP1 in my A2, should I do AQA or Edexcel? which board is easier? thanks

Guys for the gradient questions I just want to clear something up.

Say if the gradient is h+3 and as h tends to zero the gradient of the line PQ tends to the gradient of the curve at point P. Do we then have to say the gradient of the curve at point P is EQUAL to 3, or that gradient of curve at point P tends to 3?

If someone could write a general answer for this I would much appreciate it.
