I am having problems with maths formulas. 2 units are all right, but the trig identities I keep forgetting after like 2 weeks or so after doing the questions.
Does anyone have any formula sheets or somewhat like that ? I am gonna buy large papers and write the formulas in coloured pen
and then stick it on my wall. So every time I wake up I can look on them.
