Maths Formulae

    It's been a good few years since I sat the LC, and I sat Honours Maths when I did.

    I have been asked to help someone with their preparation for the Ordinary Level Paper. I am just wondering, do they still give out a sheet with the formulae on it (in addition to the tables)? Or must they all be learnt by heart? If they give a sheet, what formulae are on it? If they don't I want to make p a list of formulae he must have learned going into the exam.

    Thanks.

    Those in black are in the table book, those in red you need to learn.
