Conclusion - 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 method..

a) It is the main constituent of energy rich compounds like ADP (Adenosine diphosphate), ATP (Adenosine triphosphate), GTP (Guanine tri phosphate) etc. b) Its a major constituent of cell membrane, nucleic acid, cellular energy transfer systems. c) Essential for metabolic reactions releasi..

Introduction - Astronomy has been a fascinating subject from ancient times. The geocentric system (around the 2nd century A.D.) considered the Earth to be at the centre with the sun and other planets revolving around it. In the 16th century, Copernicus suggested the heliocentric syst..

For thousands of years people have looked up at the stars and wondered what lay beyond them. It was once believed that the earth was the center of the universe and that everything moved around it. It was later discovered that the earth moves around the sun. Today, powerful telescopes and space prob..

It is also referred to as pulse-width modulation. It varies the pulse length or duration around a fixed value. This may be done by shifting either the leading or trailing edge, or both, as a function of the sampled amplitude. Greater channel band width is required than for PAM. Design must be co-o..

refers to the process of taking instantaneous values of the message signal at regular intervals (in the case of uniform sampling.) This makes the time-frame (of the analog signal) discrete. Most pulse systems are based on sampling of the information signal amplitude at periodi..

Both living organisms and non-living matter are composed of some basic elements and are bound by the same physical laws. However, living organisms differ from non-living matter in some specific aspects. Living organisms exhibit a kind of organisation from molecular level to the organismic leve..

The position of the point P in a plane in the rectangular co-ordinate system is determined as follows: Draw PA and PB perpendicular to XX' and YY'. The segment OA = a measures the distance along the x-axis (the x-coordinate and the perpendicular distance AP = OB = b ( parallel to y - a..

The two-kingdom classification received considerable recognition from biologists and was in use for quite a long period of time. However, as more and more information started emerging on the various groups of plants and animals, this system of classification was found to be inad..
