Simpsons rule you can only have odd numbers for the equation, so my question is what do you do with the number you have to ad on in this instance y13 ? because ive been provided y1-y12 i need to add y13 to make it odd but what do i do with it ?

Area= strip width /3 ( F+ 4E+2Q)


strip width = 3.1

3.1/3 (sum of first + last ordinates + 4 + sum of even ordinates + 2 + sum of odd ordinates)

Ordinates are
y1= 30.90
y2= 31.13
y3= 31.35
y4= 32.29
y5= 32.30
y6= 32.40
y7= 33.81
y8= 34.12
y9= 35.59
y10= 36.53
y11= 37.55
y12= 38.72

y13= is this equally to 0 ?

John you need the polynomial if you want to work out other points on the line.
