What questions usually throw people off in C2 exams? Which ones are generally seen as the hardest, because they have the highest room for mistakes?

So far, I've got a list of:

Binomial Expansions
Logarithms/Inequalities
Triginometrical Equations, using the graph to find values of Theta
Identities (to an extent)
Differentiation/Integration worded questions

Any other topics that would need to be brushed up on before the exam, or any more information anyone has, would be *greatly* appretiated. Thanks. =)

Im planning on doing a lot of revision today, I just don't know exactly what I need to focus on to ensure I won't be caught out during the exam.

i think they give you a formula for bionomial expansion and also logs
other than that i would say trig identites yucccck

C2 trig identities? There are only two to learn (at least on edexcel).

[wanderlust.xx]

Applying them is the slightly difficult part due to the squares and minus/plus signs etc etc.

WOT? aint it just sin^2(0) + cos^2(0) = 1

For me i can't get my head around radians

[prash_s90]

trig identity is easy...i would say the geometric wordy questions are harddd

[amtheo]

radians are easy i just think of them of big degrees

[EvenStevens]

Radians are easy if you know the equivalences.

i.e.







=D

And there's only two trig identities to learn for C2, and they've already been said.

If you hate trig identities now, just wait 'till you get to C3.

Oooh, boy

[Alessandro_22]

oh i meant questions related to arc and finding the lengths etc..? any help guys?

[Daniel Freedman]

What do you find difficult about it?

Arc length is given by:

Area of a sector is given by:

Area of a segment is given by .

These can all be worked out easily from the definition of the radian anyway (the first literally is the definition, just rearranged).
