some applications of areas are shown. Using CAD (computer-assisted design), an architect programs a computer to sketch the shape of a swimming pool designed between the curves $y=\frac{800 x}{\left(x^{2}+10\right)^{2}} \quad y=0.5 x^{2}-4 x \quad x=8$ (dimensions in $\mathrm{m}$ ). Find the area of the surface of the pool.

Key Concepts

Definite Integral

A definite integral is a fundamental tool in calculus that computes the accumulation of quantities, such as areas under a curve, over a specified interval. By evaluating the definite integral of a function between two bounds, one can determine the total area, net change, or other accumulated values that the function represents.

Area Between Curves

The concept of the area between curves involves calculating the difference between two functions over a common interval. By setting up an integral of the difference between the top and bottom functions with respect to the independent variable, one can determine the exact area confined by these curves.

Intersection Points

Finding intersection points is crucial when determining the boundaries of the region of interest. These points indicate where the functions meet, and thus help in accurately determining the limits of integration needed for calculating areas or other quantities based on the graphical representation of the curves.

Computer-Assisted Design (CAD)

Computer-Assisted Design (CAD) is a technology that utilizes computer software to create precise drawings and models of physical objects. In the context of geometric applications, CAD aids in the simulation, analysis, and visualization of complex shapes, streamlining the process of defining regions and calculating their properties such as areas.
