determinant method

We have seen the application of matrices and determinants in solving system of linear equation with three unknown variables. Matrices and determinants are also widely used in solving large system of linear equation. Some of these methods are Gauss-elimination meth..

The argument (P 1 , P 2 , P 3 .....P n ;Q) is said to be valid if Q is true whenever all P 1 , P 2 , P 3 .....P n are true. We discuss two methods to determine the validity of the argume..

Quantitative Analysis - Determination of the relative proportions (as percentages) of various elements present in an organic compound is called quantitative analysis of the compound. The percentages of the various elements present in the compound are estimated by suitable chemical me..

Introduction - Organic compounds are isolated either from natural sources or from reaction mixtures. These compounds are seldom pure and are usually contaminated with small amounts of other similar compounds, which are found to exist together or formed during the reaction. In order to characterize ..

Determination of the relative proportions (as percentages) of various elements present in an organic compound is called quantitative analysis of the compound. The percentages of the various elements present in the compound are estimated by suitable chemical methods as desc..

Types of linear systems Gauss-Jordan elimination, Gauss-Jordan method Vectors and vector addition Geometrical solution sets of systems of equations Rectangular matrices to row echelon form Matrix multiplication Inverse to a square matrix Determinants of 2 by 2 and 3 by 3 mat..

Relative density of solids like wax, cork etc. is determined by the following method. Choose a sinker and find its weight in water by suspending it in water as shown in figure (a) below. Tie the solid cork to the string attached to the sinker and find its weight in air but sinke..

Bond length is the average distance between the centres of the nuclei of two bonded atoms in a molecule. It is expressed in Angstrom units () or picometers(pm). 1 = 10 - 1 0 m and 1pm = 10 - 1 2 m. It is determined with the help of X-rays diffraction and other spectroscopic met..

The identification and characterization of an organic compound such as molecular formula etc., must have the compound available in pure form. The process of obtaining the compound in its purest form from an impure sample or from any reaction mixture is called purification. Methods of sepa..
