    Formula//
    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

    In addition to the above formulae:

    Median of a data set: (n+1)/2 where n is the variable pertaining to (total) frequency
    Pressure = Force / Area
    Speed = Distance / Time
    Exterior angle = n/360
    Sum of interior angles: (n-2) x 180
    Area of a Sector: (some given angle)/360 x Pi x radius squared
    Length of an arc: (some given angle)/360 x Pi x diameter
    Perimeter of a sector: (some given angle)/360 x Pi x diameter + 2r
    Volume of a sphere: 4/3 x Pi x radius cubed
    Surface area of a sphere: 4 x Pi x radius squared
