In a geometric sense, it is convenient to think about the integral of a two-dimensional function in a certain section as the area of a figure closed between the graph of this function, the X-axis, and straight lines corresponding to the selected interval perpendicular to it. With these formulas, he performs a calculation equivalent to the calculation of a certain integral: In 1615 he wrote the essay Stereometry of Wine Barrels, where correctly calculated a number of areas, for example, the area of a figure bounded by an ellipse and volumes, while the body was cut into infinitely thin plates. Now, if we consider integrating over a finite domain, the limits are as follows: \[ \int_{a}^{\infty} f\left( x \right)dx = \lim\limits_{n \to \infty } \int\limits_a^n f\left( x \right) dx\].
