Expert Answer:

Dear Student,

Given a function ƒ of a variable x in an interval [ab] , the definite integral

is defined informally to be the net signed area of the region in the xy-plane bounded by the graph of ƒ, the x-axis, and the vertical lines x = and x = b.

once an antiderivative F of ƒ is known, the definite integral of ƒ over that interval is given by

There are various rules to find the 'anti-derivative' of a function f(x), that are used to calculate the value of an integral.
