tanx=sinx/cosx

sin^2x + cos^2x = 1

The cast diagram that loads of people use but I STILL dont understand

ermm.... you kinda supposed to be able to apply knowledge so radian measure etc... would be useful for some questions maybe.
3. but no need to remember other formulas like geometric/arithmetic/area of sector etc rite?

A past paper from P3 did actually use the sector/arc formulae so I think you do have to know all the previous ones
6. P2 exams suppose a knowing of P1, P3 supposes knowing of P1, P2 and so on.....
