Trapezium Rule

Formula of area of a trapezium=½(a+b)h
The formula to work out the area under a curve is:
A=1/2(y0+y1)h+1/2(y1+y2)h+1/2(y2+y3)h...
Note: the small numbers show which line you are referring to, in the below
example, y0 is at x=0, y1 is at x=1.

Therefore the area under the curve is roughly 22, however this is not accurate
because there are only 4 trapeziums: to increase accuracy, increase n (the
number of lines).
