solve using matrices

In the previous post we have discussed about 11th Grade Math and In today's session we are going to discuss about solve using matrices. Matrices are defined as the set of objects or set of numbers or may be a set of characters in the form of a particular format of rows and columns. These rows and columns are defined for all matrices and a matrix is also known as two dimensional arrays. Various operations can be performed over matrices that are mathematical operations such as addition, subtraction, multiplication and inverse of a matrix can also be determined. Matrices are defined in the order “m x n” where m is the number of rows and n is the number of columns. An equation can be represented in the form of matrix, as left hand side of equals to symbol is represented in the matrix form to the left side only and similarly the right side is represented to the right side in the matrix form. Let us consider an example with the equations x + y = 5 and 3x – y = -1. These equations can be represented in the form of matrix and we will solve using matrices. Representing these equations in the form of matrix we get coefficients of x and y in one matrix and x and y in other matrix. And the constants will be represented to the right hand side in the form of matrix.

Potential energy is defined as the energy which is in the form of stored energy. Potential energy formula is given as potential energy is equals to the product of mass of object to the acceleration of gravity to the height of object. In a mathematical form it is represented as P.E= m x g x h where m is the mass of object, g is the acceleration due to gravity and h is the height of object. Icse board is similar to cbse board which runs all over India. It appears to give more practical knowledge and icse 2013 board papers can be easily discovered on net. It provides help to the students by giving an idea of questions.
