Simpson's 1/3 Rule Numerical Integration

Simpson's 1/3 Rule Numerical Integration is used to estimate the value of a definite integral. 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.

b∫aIn x dx = h/3 [(y0 + y5) + 2(y2 + y4) + 4(y1 + y3)]
Where 'x' is an equation 'a' refers Upper Limit and 'b' refers Lower Limit.
