I need to know - which formulas will you need to remember for tomorrow's exam and which ones will be given to you in the formula book ? Going through the book, there seems a lot you have to remember. I haven't been paying much attention in classes recently, for various reasons, so in the probable event that I f#@! up tomorrow, how bad would this be, taking into account retakes etc (I got 99 in C1). What things would you suggest I revise or specifically concentrate on in preperation for tomorrow ?


Cheers.

Un=arn-1
Sn= [s(1-rn]/1-r
Sinfinitea/(1-r)
l=r(theta)
Asector=1/2r2theta
Asegment=1/2r2(theta-sin(theta))
sin2x+cos2x=1
sinx/cosx=tanx
(x-a)2+((y-b)2=r2 where (a,b) is the centre of the circle...
the quadratic formula
sin and cos rules
and thats all i can remember.. hope that helped!

PS: Its no point just memorising the formula... you should at least know how to apply them to the question... trust me... you have do atleast two past papers.. good luck

and all the C1 and GCSE formulae including volumes and surface area of various shapes...You should revise everything... If you think you are capable of doing most of the questions, do some more question on integration and differentiation... they are bound to come up!

OK i might be wrong... so who said that... I thought you had to memorise those formulae as well and i have seen past exam questions on it...

Also worth at least looking over the proofs for geometric series.

download the formula book, u get nearly all you need.

You get the cosine rule (in 1 form)

All the Geometric series stuff youll need
- Un, Sn and S to infinity

You get the trapezium rule

You get binomial series stuff which theyve made look complex but its just the basic thing

you get 1 log rule : how to change the base thingy. You know loga B = log B over log a

Youll need to remember all the radian stuff, the trig identities, some more trig, circle theorem formula if there r any and thats about it. And try to remember the sin30 = whatever radians and cos 60 etc etc

tbh if youve got a graphical calculator just write it in...
