Math - Essay ExampleThe first example is from Physics. Suppose that we are disposed(p) three objects, one with a known mass of 2 kg, and are asked to find the unknown masses. Suppose further that experimentation with a meter thwart publishs these two correspondences.Since the sum of moments on the left of each balance equals the sum of moments on the right (the moment of an object is its mass times its distance from the balance point), the two balances give this outline of two equations (Hefferon).The second example of a linear dodge is from Chemistry. We can mix, under controlled conditions, toluene C7H8 and nitric acid HNO3 to produce trinitrotoluene C7H5O6N3 along with the byproduct water (conditions have to be controlled very well, indeed-trinitrotoluene is better known as TNT). In what proportion should those components be mixedOur attached example is about solving a riddle. There are two groups of people X and Y having certain number of persons in each group. If a person from X leaves to join Y then Y expires double of X. If a person leaves Y to join X then they both become equal to each other. How many persons are there in each groupThe objective is to determine if such system of linear equations has a source or not. That is to find out if there exist values of x1 to xn which when fed into these equation will simultaneously satisfy all the equations. If true then the system is said to be consistent or else it is inconsistent (Matthews).MATRICESThe above system of equations can also be briefly compose as,The intercellular substance is called the coefficient matrix of the system of equations as it only has the coefficients of variables listed in it. If this matrix were also to include the constants involved in the equations then it would be called an augmented matrix of the system and would be written as,Three elementary quarrel operations can be performed on matrices which do not affect the solution of linear equations.1. Interchanging two row s2. Multiplying a row by a non-zero number3. Adding a multiple of one row to anotherWe will try to solve the following equations with the help of a matrix and then applying any or all of the appropriate elementary row o
