Concept explainers

Optimization

Optimization comes from the same root as "optimal". "Optimal" means the highest. When you do the optimization process, that is when you are "making it best" to maximize everything and to achieve optimal results, a set of parameters is the base for the selection of the best element for a given system.

Integration

Integration means to sum the things. In mathematics, it is the branch of Calculus which is used to find the area under the curve. The operation subtraction is the inverse of addition, division is the inverse of multiplication. In the same way, integration and differentiation are inverse operators. Differential equations give a relation between a function and its derivative.

Application of Integration

In mathematics, the process of integration is used to compute complex area related problems. With the application of integration, solving area related problems, whether they are a curve, or a curve between lines, can be done easily.

Volume

In mathematics, we describe the term volume as a quantity that can express the total space that an object occupies at any point in time. Usually, volumes can only be calculated for 3-dimensional objects. By 3-dimensional or 3D objects, we mean objects that have length, breadth, and height (or depth).

Area

Area refers to the amount of space a figure encloses and the number of square units that cover a shape. It is two-dimensional and is measured in square units.

Creating graphs gives you a picture of your data. In our visual-oriented world, graphing data is one way of "letting the statistics speak for themselves." The proper choice of graph depends on the nature of the variable. Most graphs are pie charts, bar graphs, histograms, frequency polygons or timelines. There are others, but in these are the graphs you will see most often in media, public opinion polls and research studies. A histogram usually has vertical bars placed on the horizontal axis (x-axis) that touch each other, although some texts no longer require that the bars touch. The y-axis shows the frequency, percetage or rate of occurrence. Figure 1.
