There are two main methods.
One is the trapezium method. Here the integral ("area under the curve") is split into a large number of trapeziums with their parallel sides being vertical. The areas of these trapeziums are calculated and added together to approximate the integral. The greater the number of trapeziums the more accurate the answer but also the more effort is required.
Another approach, which can sometimes work, is to find two integrable functions such that one of them is greater than the function to be integrated and the other is less. If the required function can be tightly sandwiched between two such functions then the integral of the function will be between the integrals of the two integrable functions. Even if you cannot find two such functions that fulfil this requirement over the whole domain, provided you can find pairs of functions that do so over all but a finite number of points is good enough. Actually, I believe it works even if the number of gaps are countably infinite (cardinality Aleph null), but I am not sure of that.
There are many approximation methods for area.
Sometimes a function can't be integrated by regular methods, or just an estimate for the integral is needed. It's silly to use Simpson's Rule for a function such as cos(x) that has an elementary antiderivative, but something like e^(-x^2) doesn't. So, you can approximate the definite integral using Simpson's Rule.
A general quintic can be solved using numeric methods. It may be an approximate solution but then even the solution to x2 = 2, in decimal terms, is approximate.
Finite Differential Methods (FDM) are numerical methods for approximating the solutions to differential equations using finite difference equations to approximate derivatives.
Two main options.Carry out numerical integration - there are various methods - the trapezium method being one of the simpler ones; orfind two integrable functions such that one is greater than the given function and the other is smaller than it. Then your integral will lie between the integrals of these two functions.

Procurement performance is an activity or an integral component of integral procurement management. It involves in describing key indicators, methods, and processes that are necessary for measuring the procurement success.
