Integrating Equations

Many problems in mathematics, science, and engineering require calculating the
definite integral of a function– If the function is denoted by f(x) and the interval of
integration is a to b, then the integral can be expressed mathematically as
The quantity I can be interpreted geometrically as the area of a region bounded by
the graph of the function f(x), the x–axis, and the limits x = a and x = b (provided
that f(x) is nonnegative throughout the interval of integration).
