How to use the integral function?
Integration is part of the important concepts that are associated with mathematics and is part of the main operations in calculus. It has to be given the function f of a variable x that is real, as well as the interval which is a, b, of that real line, and this is the definite integral:
This has been informally defined as the signed area of a region that is in the x/y-plane and has its boundary defined by a graph of f, the x-axis, as well as vertical lines x that is a, and x that is equal to b. The term known as integral could also refer to the related notion of antiderivative, which is a function F whose derivative is the function that is given. In such a case, an indefinite integral is defined and also written like this:
