Does edexcel expect you to know about even and odd functions?
I know exactly what they are, just came across a question about them in a C3 edexcel practice paper.

Yes. The question has come up often.

I can't say at exactly which C level, since I did the P papers.

yep - its handy to know it although you may not use it to great extent, but its very necessary to know it for P6 if you do further maths because you have to use it a lot for series and the algebraic manipulation that you do in it - and you need all that stuff about sum product formulae, and other trig identities in M4 P5 and P6 so learn them well

it came up in a past paper but i'm pretty sure its not in the textbook - so i doubt they'll still ask it

doesn't seem to be a whole lot to it though (based on that 1 question anyway), maybe worth glimpsing at it

If a function is even, then f(-x) = -f(x)
If a function is odd, then f(x) = f(-x)

other way round.
