sorry to say this, but ur screwed.

You shouldnt be learning at all when revising. When you look at something u dont know, u start 2 panic, if u know what i mean.

You can try, but trust me, u either get pure1 or you dont. There is no guessing !

get yourself revision book for pure1, or better try doing past paper questions... once you've done a couple of them, you'll be fine!

what exam board you've got?

Ermm... Im not doing P2 yet, and im with EDEXCEL, but its fairly standard proof really.

Its hard to write on a board post though.

if you wanna get a good grade in pure 1, you should do about 5 or maybe 6 past papers, and make sure you do one as a mock. you can do it by yourself! trust me, thats what i did for my revision and got an "a".
good luck matie!

The standard method for proving identities is to consider one side of the identity and transform it to the other side by manipulating it alone. For example, say we had the simple identity (I use '=' instead of the identically equals sign, and b^2 is 'b squared'):

(x + a)^2 = x^2 + 2ax + a^2

Well, we need to decide on one side to work with. Let's try the left hand side, as it's often easier to expand than it is to factorise. LHS mean left-hand-side and RHS means right-hand-side, so:

LHS = (x + a)^2
= x^2 + ax + ax + a^2
= x^2 + 2ax + a^2
= RHS

Hence the identity is proved. We have manipulated one side of the identity until it is in the same form as the other side, hence they are identically equal. Obviously this was a very simple example, but it should help you to get a clearer idea of what's going on.

If you have any specific questions you can't do, feel free to post them here.
