A biochemist is testing the effect of a new antibiotic on a particular bacteria growing in a petri dish. Without the antibiotic the bacteria grows as a circular patch with the radius increasing with time according to r = 0.5t cm, where t is measured in hours since the bacteria was introduced to the petri dish. The area of the bacteria is given by A = rr2, the area of a disc of radius r. When the radius of the disc reaches 2 cm the biochemist introduces the antibiotic. This causes the radius of the disc to reduce according to r = 2 - v t cm, where t is measured in hours since the antibiotic was introduced. (a) What was the time duration of the entire experiment (from the introduction of the bacteria until its disappearance)? (b) Graph the radius of the disc against elapsed time since the start of the experiment. (c) How fast was the area of the disc increasing (cm2 /hour) just before the antibiotic was introduced? (d) What was the maximum area of the disc? (e) ow fast was the area of the disc decreasing (cm2 /hour) just as the disc disappeared due to the antibiotic?
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.
