What is Definite Integral

The definite integral is the difference between the values of the antiderivative for the integrand. Simply put, a certain integral is numerically equal to the area of a part of the graph of a function within certain limits, that is, the area of a curvilinear trapezoid. The definite integral can be calculated using the Newton-Leibniz formula. This calculator solves the definite integral of f (x) with given upper and lower limits. Using an online calculator for calculating definite integrals (area of a curved trapezoid), you will receive a detailed solution to your problem, which will allow you to understand the algorithm for solving problems and consolidate the material covered.
