Question

What is simpson's 1/3 rule for area calculation?

Answer 1

To find the area of an irregular boundary, Simpson’s 1/3 rule is used.  

Simpson’s rule assumes that the irregular boundary is composed of parabolic curves  

As per Simpson’s 1/3 rule,

Area =$\frach3$(First Value + last value + 4× (Sum of odd values) + 2×(Sum of even values)  

The below condition needs to be taken care of when using Simpson’s rule

The interval must be an even number

Minimum of three points is needed to use this rule

Intervals must be even for all the values
