Trapezoidal / Trapezium Rule Approximate Numerical Integration



Trapezoidal / Trapezium Rule is a method of finding an approximate value for an numerical integral, based on finding the sum of the areas of trapezia. Trapezium rule is also known as method of approximate integration. A slight underestimate will often be cancelled by a similar slight overestimate from another trapezium. Using narrower intervals will improve accuracy.

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