CHAPTER 02.02: VECTORS: What is a vector? Example

 

In this segment weíll look at an example of a vector. Letís suppose many times we say ďHey somebody gives us a coordinate on a particular spaceĒ and they will say okay these are the values of x, y and z also somebody says hey the values of x, y and z are 7, 13, and -23 for example. How do we write this in a vector form so all we have to do is to simply say hey I got a vector letís suppose called the A-vector and this is my x, y, and z so I will write this as 7, 13 and -23 as my vector so here Iíve written the coordinates of a particular point in space as a column vector and this one has three elements in it 1, 2, 3 so thatís why we call it a 3-dimensional we call it a 3-dimensional column vector and thatís an example of a vector. And thatís the end of this segment.
