what does the integral f x dx represent Definition Definite Integral If f x is a function defined on an interval a b the definite integral of f from a to b is given by b af x dx lim n n i 1f x i x provided
Definite Integral Given a function f x that is continuous on the interval a b we divide the interval into n subintervals of equal width x and from each interval choose a point We call the function latex f left x right latex the integrand and the dx indicates that latex f left x right latex is a function with respect to x called the variable of integration Note that like

The integral sign is the continuous version of the sum sign The bounds of integration from a to b are like the first and last x values for the summation And the dx is the infinitesimal version of x what we get when we take smaller The definite integral has a unique value A definite integral is denoted by a b f x dx where a is called the lower limit of the integral and b is called the upper limit of the integral
