CHAPTER 1 INTRODUCTION 1.1 INTRODUCTION Transport along with communication‚ forms the core of day to day life of modern world. Conventional rail transport through wide spread is now being considered inefficient in terms of fuel consumption and is time consuming. A genuine replacement for railways which is not only fuel efficient but also highly comfortable and can attain unimaginable velocities of around 450 – 500kms/hr are Maglev Trains whose idea was given by Robert Goddard‚ an American

Figure 1.1: The slope of a line (usually given the symbol m) is the ratio of the change in the y value‚ ∆y to the change in the x value‚ ∆x. We define the slope of a straight line as follows: Slope = ∆y ∆x v.2005.1 - September 4‚ 2009 1 Math 102 Notes Chapter 1 where ∆y means “change in the y value” and ∆x means “change in the x value” between two points.

Characteristics of a circuit using an op-amp are set by external components with little dependence on temperature changes or manufacturing variations in the op-amp itself‚ which makes op-amps popular building

Dividend Policy at Linear Technology Of the 16 companies on the SOX index‚ six paid dividends and Linear Technology is one of them started at the second quarter in 1993 which is 5.3 million in total. However‚ in the case‚ according to Coghlan‚ “The quarterly dividend was initially set at $0.05 per share. This amounted to $8.3 million‚ or 15% of FY 1994 earnings.” And their most recent dividend in 2002(cause in the exhibit2‚ there’s only threes quarter’s data in 2003‚ so that’s why I choose 2002

In Mathematics‚ a periodic function is a function that repeats its values in regular intervals or periods. Periodic functions are used throughout science to describe oscillations‚ waves‚ and other phenomena that exhibit periodicity. Periodic functions are those that repeat on a set interval. All trigonometric functions are periodic. They are useful because one can determine the value of the function anywhere in the domain. If a function is periodic‚ then there is some value n for which

I think that many math topics have meaning and relevancy and are dependent on the path one takes in terms of finding real world application. For example‚ sports is largely dependent on sports. Decisions are made based regarding playing time as well as strategy based on percentages. In baseball‚ there is a strong use of math. Managers have to make decisions on which pitchers to start and‚ especially so in games of importance‚ those decisions are predicated upon statistical reality. If a pitcher has
