Numerical integration using Weddle's rule calculator
1. From the following table, find the area bounded by the curve and x axis from x=7.47 to x=7.52 using Weddle's rule.
x7.477.487.497.507.517.52
f(x)1.931.951.982.012.032.06

2. Evaluate I = 6011+xdx by using Weddle's rule with h=1 or N=6


Example
1. Find Solution using Weddle's rule
xf(x)
7.471.93
7.481.95
7.491.98
7.502.01
7.512.03
7.522.06
7.532.09


Solution:
The value of table for x and y

x7.477.487.497.57.517.527.53
y1.931.951.982.012.032.062.09

Using Weddle's Rule
ydx=3h10[y0+5y1+y2+6y3+y4+5y5+y6]

ydx=3×0.0110[1.93+5×1.95+1.98+6×2.01+2.03+5×2.06+2.09]

ydx=0.1204

Solution by Weddle's Rule is 0.1204
