Show Simple Trapazoidal rulep.7-1 Composite Trapazoidal rule p.7-1

and

Show Simple Simpson's rule p.7-2 Composite Simpson's rulep.7-2

Solution

edit

Composite Trapezoidal rule

From Simple trapezoidal rule we have ,


similarly we have

. . . .

Summation of all of above expression gives

Hence Proved..

Composite Simpson's Rule

From Simple Simpson's rule we obtain ,

where

Similarly

. . . .

After Summation of above terms we obtain


where n = 2k and k = 1,2,3,4.....

Hence Proved
