Simpsons 1/3 Rule Calculator

Simpson's 1/3 Rule is used to estimate the value of a definite integral. It is a method for numerical integration. It works by creating an even number of intervals and fitting a parabola in each pair of intervals. Simpson's rule provides the exact result for a quadratic function or parabola.

baIn x dx = h/3 [(y0 + yn) + 2(y2 +.... yn-2) + 4(y1 +..... yn-1)]
Where 'x' is an equation 'a' refers Upper Limit and 'b' refers Lower Limit.
