So how are we all feeling about this one after C1 today? :biggrin:

btw has anyone ever seen a question about proving the sum formula for arithmetic and geometric in a past paper?

C1 was a bum thanks for asking :tongue:

still i have to have done better than first time round...

you never have to do that kind of proof, proving formulas etc...
however i did just do a question which gave you an equation for the sum of a specific geometric sequence and you had to show how they got it by using the given formula from the formula book... other than that you dont have to show HOW to get the formulas i dont think :smile:

So much fun for me...
Stupid timetabling by MEI.

Does anyone understand how to do the logs for the question 12 on the january 11 paper?
It would be so helpful if you could explain it, i've looked it up in textbooks, online ect and I just don't understand what to do after drawing the graphs! I know all the long rules, and i understand the first bits :smile:

I found it in the textbook, just be calm and read pages 326-338. :biggrin:

hoping to get some revision done tonight, more exams this afternoon. I've got to do well on C2 and M1 now - if C2 is difficult I could be screwed!

can anyone help me with the trapezium rule please?

I can use and apply the rule well but there are certain questions where I ALWAYS lose marks which is when they ask you to 'use rectangles to calculate a lower/higher bound'? What do I do to do this? :s-smilie:

e.g. January 2010 Q11ii)

Also I'm really poor at explaining whether it's an over/underestimation - I know that a concave shape gives an overestimate and vice versa but can't explain this using a diagram or with any more detail than 'it's concave therefore an overestimate'. Could anyone help with this please?

C1 section B seriously made me think that I've done something wrong and was being punished.

If C2 is as bad as that then I defiantly have done something wrong =|

Do we need to know about cancellation laws for logarithms :s-smilie:

Well this is the formulae booklet - everything for C2 is on pages 1-3

http://www.mei.org.uk/files/pdf/formula_book_mf2.pdf

I know we are not given the trigonometry rules eg sin^2x=1-cos^2x or area of segment etc
