    If you're on the OCR exam board, I can post a link for you in the next few minutes with a list of formulae which are given to us and ones which are not given to us.

    Ah sorry, I completely forgot to post the link until now.

    Here is the link: http://www.ocr.org.uk/Images/294471-...-handbook-.pdf

    The pages I mentioned are from page 59 to 66 onwards.
