    tanx=sinx/cosx

    sin^2x + cos^2x = 1

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

    ermm.... you kinda supposed to be able to apply knowledge so radian measure etc... would be useful for some questions maybe. :confused:

    A past paper from P3 did actually use the sector/arc formulae so I think you do have to know all the previous ones :rolleyes:
