Trapezoid Rule: Trapezoidal rule is used to find out the approximate value of a numerical integral, based on finding the sum of the areas of trapezium. It is also known as Trapezium Rule or approximate integration method. A small overestimate can cancel slight underestimate from another trapezium. Here narrower intervals are used to improve accuracy.
The trapezoidal rule can be depicted as :
b∫aIn 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.
Approximate numerical integration is described through the numerical value. Using this free online trapezoidal rule calculator you can calculate the trapezoidal or trapezium value with ease.
