First off, the question is based around derivatives, including cos, sin, sec, etc (year 12 specialist mathematics). The question asks to find a set of equations related to the 50m arc of an Aussie rules football oval, this is basically an arc of a circle with radius 50m, the width of the goals are 6.4m and I need to find a set of equations relating the rate of change of an angle. This angle is the angle between one goal post to another from a point 50 metres away.
