The approximated integral value

Parent Previous Next

f referring to a previously defined function, you can create the approximated value of the integral of f from a to b through Simpson method.


This integral value will be characterized by a name, the associated function, a and b values and value of  n (number of subdivisions of the interval will be 2n)).

Values of a, b and n may be dynamic.

An integral value is created via menu Calculus - New real calculus - Approxiated integral value.


To be noticed :

Practically, for an interval of reasonable length and a function rather regular, the default value n = 20 gives good results.
