Soh Cah Toa helps me best - just write it at the top of your page every time you attempt a question.

Pythagoras' theorem...for me, it just comes up so often it's drilled into my memory...as far as I know its in our log books.

Also remember special triangles, inverse sin/cos/tan (when getting the angle) and try lots of problems. (sorry don't know if you're HL or OL?)

type in "getting Triggy with it" on youtube....a high school in the US is using rap to show maths is fun

My maths teacher taught us a funny way of remembering sin, cos and tan

Sin: Silly Old Hitler

Tan: Troops Over Asia

Pythagoras theorem is as easy as ABC!

a^2 = b^2 + c^2

(just remember, 'a' is the longest side)

Hope it helps :)
