10. Background information for those interested in the historical development (you may skip this first paragraph and go straight to the question in the second para- graph if you are not interested in the history): Consider a curve defined as follows: Draw a fixed circle of radius centered at (0, ). Label the top point of the circle (0, 1) as M, and the bottom point (0, 0) as O. Draw the top horizontal tangent line to the circle at M. For any other point A on the circle, a secant line OA is drawn. The line OA intersects with the top horizontal tangent line at the point N. The verticle line through N and the horizontal line through A intersect at P. As the point A is varied along the circle, the path 1 of P traces out a curve, for which its Cartesian equation is given by y = the famous Witch of Agnesi, named after a brilliant Italian mathematician Maria Gae- The is x² + 1 tana Agnesi (1718-1799) who published her work Instituzioni Analitiche in 1748, which includes the study of this curve versiera (Latin vertere). Instituzioni Analitiche is the first surviving mathematicial work written by a woman, and it is over 1000 pages. It is believed that there was a mistranslation from the original text into English, that the word versiera was mistaken as adversarius (the wife of the devil), and thus, resulted in the association of the name Witch. Before Agnesi, the curve was first appeared in the works of Fermat in 1 1630. Later in 1824, the curve y = (multiplied by a factor of ), was re-visited T(x² + 1) by Poisson as a probability density function, aiming to provide a counter-example to the earlier version of The Law of Large Numbers by Laplace in 1810. This is now commonly known as the Cauchy distribution, for which the mean, the variance, and any higher order moments do not exist. Question: Find the unbounded area between the Witch of Agnesi y = 1 and the x² +1 x-axis.
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.
