Integration is the calculus of finding the 'integral' of functions. An integral is essentially the accumulation of quantities, and it is widely used in scenarios involving areas, volumes, central points, and many more applications in physics and engineering.
Integration can be understood as the inverse process of differentiation.
While indefinite integrals represent a family of functions, definite integrals compute the area under the curve of a function within a specified interval.
"Integration is like assembling Lego blocks to create a magnificent structure."
