Math Vectors

MIchael Driesen Mrs. Rozell Math 10H 17 December 2011 Vectors Math is e rattlingwhere. No yield which way you look at it, its there. It is especially wassail in science. Most people dont line up it, they stupefy to look closer to find out what it is actually made of. A component in math that is very prominent in science is the vector. What is a vector? A vector is a geometric object that has both a magnitude and a direction. A good example of a vector is wind. 30 MPH north. It has both magnitude,(in this case speed) and direction. Vectors have specific properties that make them very useful in really life applications. Through the use of these special objects, many advancements in the fields of math and science are available. Representations Vectors can sometimes be hidden behind basic objects. They are ordinarily represented with an arrow on top of its starting foreland and close bear witness, as shown here: The most common tier of vector is the intimidate vector. All that means is that the starting point of the vector is the origin, or (0,0). The bound vector goes from the origin to its terminal point, which in this case can be (3,4). An loose way to write this is A = (3,4), where A is the vector.

On a graph, it looks like this: That applies for two-dimensional vectors. Three dimensional vectors can be represented that way also. In a 3 dimensional vector, its terminal point has coordinates in three axis. These points can be represented by the letters i, j, and k. The letter i is for the x axis, j for the y axis, and k for the z axis. An example of a 3 dimensional vector is written as: A = 6i+3j+4k. It can also be denoted as A = (6,3,4). Where (6,3,4) is the terminal point. Two vectors are equal if their coordinates are equal, so if an some other(prenominal) vector, say B, had the terminal point (6,3,4), and if both vectors are bound vectors, they would be equal. Aside from direction, a vector has one other part, which is magnitude. Magnitude is denoted by the original vector... If you want to get a full essay, order it on our website: Orderessay
