It's just the approximation of a curve, by selecting points at constant x intervals from each other. The rule then calculates out the area of each trapezium created and this is an approximation to the total area under the curve

whats the equation for the trapezium rule?

h/2 [ y1 + 2y2 + 2y3 + 2y4 + y5 ]

if there's equal different segments, and "h" being the common difference?
