C OORDINATE GEOMETRY COORDINATE GEOMETRY 155 7 7.1 Introduction In Class IX‚ you have studied that to locate the position of a point on a plane‚ we require a pair of coordinate axes. The distance of a point from the y-axis is called its x-coordinate‚ or abscissa. The distance of a point from the x-axis is called its y-coordinate‚ or ordinate. The coordinates of a point on the x-axis are of the form (x‚ 0)‚ and of a point on the y-axis are of the form (0‚ y). Here is a play for you. Draw a set

1958‚ where he became a professor at McMaster University in Hamilton‚ Ontario. Developed in 1957 with Ronal Nyholm‚ Gillespie has done extensive work on expanding the idea of the VSEPR model of molecular geometry. The theory they created is much more effect to predict‚ explain and describe the 3D molecular shapes (linear‚ pyramidal‚ cubical etc.) based on the number of electron pairs that are found on the outer shell. Their theory is based on electron repulsion of bonded and unbonded electron pairs

MOLECULAR DETECTION OF FUNGAL DISEASES INTRODUCTION With the rise of many new diseases caused due to viruses‚ bacteria and fungi; it is essential for the rapid detection of such diseases. The severity of such diseases can be reduced by its rapid detection carried out by different methods. The conventional methods may include the idea of just identifying the disease symptoms‚ identification of these pathogens in the laboratory by different morphological and biochemical tests‚ etc [1]. The conventional

Introduction Vibration spectroscopy is one of the most important tools for the accurate determination of molecular structure. Vibration spectroscopy also plays an important role in environmental chemistry. For example‚ the albedo of the earth’s atmosphere is controlled by the absorption of infra-red light by green house gasses‚ which include CO2‚ H2O‚ and CH4

When it comes to Euclidean Geometry‚ Spherical Geometry and Hyperbolic Geometry there are many similarities and differences among them. For example‚ what may be true for Euclidean Geometry may not be true for Spherical or Hyperbolic Geometry. Many instances exist where something is true for one or two geometries but not the other geometry. However‚ sometimes a property is true for all three geometries. These points bring us to the purpose of this paper. This paper is an opportunity for me to
