    Topics// what you have been studying these past two years, no? for last minute revision I'd focus on the topics you struggle with (everything, in my case)

    Area of a triangle= bxh divided by 2 & 1 half ab sin c
    Cosine Rule, a2=b2+c2-2bccosA
    Sine Rule, sin A over a equals sin B over b which is equal to sin C over c
    Pythagoras, a2=b2+c2
    Trig, SOH CAH TOA

    Circumference of a circle, pi x diameter
    Area of a circle, 2 x pi x r2

    volume of a cuboid = l x w x h
    v of prism = area of cross section x length
    v of cylinder = pi r2 x h
    v of a pyramid = 1/3 x area of base x h

    parallelogram area= bxh
    rectangle area= lxw
    area of a trapezium= 1/2 a+b x h

    quadratic formula = (-b plusminus the square root of b2-4ac) divided by 2xa
