Formula

1. Weddle's Rule `int y dx = (3h)/10 [(y_0+5y_1+y_2+6y_3+y_4+5y_5+y_6)+(y_6+5y_7+y_8+6y_9+y_10+5y_11+y_12)+...]`

Examples
1. Find Solution using Weddle's rule

x	f(x)
7.47	1.93
7.48	1.95
7.49	1.98
7.50	2.01
7.51	2.03
7.52	2.06
7.53	2.09

Solution:
The value of table for `x` and `y`

x	7.47	7.48	7.49	7.5	7.51	7.52	7.53
y	1.93	1.95	1.98	2.01	2.03	2.06	2.09

Method-1:
Using Weddle's Rule
`int y dx=(3h)/10 [(y_0+5y_1+y_2+6y_3+y_4+5y_5+y_6)]`

`int y dx=(3xx0.01)/10 [(1.93 + 5xx1.95 + 1.98 + 6xx2.01 + 2.03 + 5xx2.06 + 2.09)]`

`int y dx=(3xx0.01)/10 [40.14]`

`int y dx=0.1204`

Solution by Weddle's Rule is `0.1204`

Method-2:
Using Weddle's Rule
`int y dx=(3h)/10 [(y_0+5y_1+y_2+6y_3+y_4+5y_5+y_6)]`

`y_0=1.93`

`5y_1=5*1.95=9.75`

`y_2=1.98`

`6y_3=6*2.01=12.06`

`y_4=2.03`

`5y_5=5*2.06=10.3`

`y_6=2.09`

`int y dx=(3xx0.01)/10*[(1.93+9.75+1.98+12.06+2.0310.3+2.09)]`

`int y dx=(3xx0.01)/10*(40.14)`

`int y dx=0.1204`

Solution by Weddle's Rule is `0.1204`
