Mobile Entertainment for Your Automobile essays

Mobile Entertainment for Your Automobile essays To your left, you hear Boyd Tinsley on the violin and to your right you hear Leroi Moore on the saxophone. Behind you hear the bass guitar that Stefan Lessard commands, as the beating of drums continues from Carter Beauford. Nothing can compare though to the clear voice, that is right in front of you, of Dave Matthews. You swear he is sitting next to you in your Lincoln Navigator and as you drive, singing along with him you watch his performance on your LCD monitor from the DVD player in your dashboard. All of this you can experience in an SUV of your very own with a mobile entertainment system. Many people make mistakes when building their "dream" system, though from listening to me I can help you complete a quality, sweet sounding system you can purchase at your local entertainment store. First and foremost you need to choose a proper head unit. The head unit will house the video screen, process your sound, play your music and movies, and provide control over all your audio and visual settings. In my example, I will use the new Kenwood eXcelon KVT-910DVD because of the great features and quality components it holds. This might seem like a pricey unit to select, but you will soon know you are getting your money worth when you first pop in that slick sounding DVD. This unit is capable of playing all of your audio CD's, even those you make on your PC, and also will play any DVD movie you own. It features a motorized LCD screen which negates the cost of buying an additional video monitor and already places the screen in the perfect viewing area: directly in the middle. As far as audio quality is concerned, this Kenwood is well packed with great DAC's (Digital Audio Converter's) to process the sound and a high S/N (Signal to Noise) ratio to have almost no hiss heard fro m the speakers. All of this would not be complete without the extra Dolby Digital 5.1 and DTS processor to send your movie experience through the roof. Now to cho...

Algebra Definition

Algebra Definition Algebra is a branch of mathematics that substitutes letters for numbers. Algebra is about finding the unknown or putting real-life variables into equations and then solving them.  Algebra can include real and complex numbers, matrices, and vectors. An algebraic equation represents a scale where what is done on one side of the scale is also done to the other and numbers act as constants. The important branch of mathematics dates back centuries, to the Middle East. History Algebra was invented by Abu Jafar Muhammad ibn Musa al-Khwarizmi, a mathematician, astronomer, and geographer, who was born about 780 in Baghdad. Al-Khwarizmis treatise on algebra,  al-Kitab al-mukhtasar fi hisab al-jabr waÊ ¾l-muqabala  (â€Å"The Compendious Book on Calculation by Completion and Balancing†), which was published about 830, included elements of Greek, Hebrew, and Hindu works that were derived from Babylonian mathematics more than 2000 years earlier. The term al-jabr in the title led to the word algebra when the work was translated into Latin several centuries later.  Although it sets forth the basic rules of algebra,  the treatise  had a practical objective: to teach, as al-Khwarizmi put it: ...what is easiest and most useful in arithmetic, such as men constantly require in cases of inheritance, legacies, partition, lawsuits, and trade, and in all their dealings with one another, or where the measuring of lands, the digging of canals, geometrical computations, and other objects of various sorts and kinds are concerned. The work included examples as well as algebraic rules to help the reader with practical applications. Uses of Algebra Algebra is widely used in many fields including medicine and accounting, but it can also be useful for everyday problem-solving. Along with developing critical thinking- such as logic, patterns, and deductive and inductive reasoning- understanding the core concepts of algebra can help people better handle complex problems involving numbers. This can help them in the workplace where real-life scenarios of unknown variables related to expenses and profits require employees to use algebraic equations to determine the missing factors. For example, suppose an employee needed to determine how many boxes of detergent he started the day with if he sold 37 but still had 13 remaining. The algebraic equation for this problem would be: x – 37 13 where the number of boxes of detergent he started with is represented by x, the unknown he is trying to solve. Algebra seeks to find the unknown and to find it here, the employee would manipulate the scale of the equation to isolate x on one side by adding 37 to both sides: x – 37 37 13 37x 50 So, the employee started the day with 50 boxes of detergent if he had 13 remaining after selling 37 of them. Types of Algebra There are numerous branches of algebra, but these are generally considered the most important: Elementary: a branch of algebra that deals with the general properties of numbers and the relations between them Abstract: deals with abstract algebraic structures rather than the usual number systems   Linear: focuses on linear equations such as linear functions and their representations through matrices and vector spaces Boolean: used to analyze and simplify digital (logic) circuits, says Tutorials Point. It uses only binary numbers, such as 0 and 1. Commutative: studies  commutative rings- rings in which multiplication operations are commutative. Computer: studies and develops algorithms and software for manipulating mathematical expressions and objects Homological: used to prove nonconstructive existence theorems in algebra, says the text, An Introduction to Homological Algebra Universal: studies common properties of all  algebraic  structures, including groups, rings, fields, and lattices, notes Wolfram Mathworld Relational: a procedural query language, which takes a relation as input and generates a relation as output, says Geeks for Geeks Algebraic number theory: a branch of number theory that uses the techniques of abstract algebra to study the integers, rational numbers, and their generalizations Algebraic geometry: studies zeros of multivariate polynomials, algebraic expressions that include real numbers and variables Algebraic combinatorics: studies finite or discrete structures, such as networks, polyhedra, codes, or algorithms, notes Duke Universitys Department of Mathematics.
