The 3 common methods of describing a point in a three dimensional coordinate system are Cartesian, Cylindrical and Spherical. The most simple is Cartesian but certain teachers find it necessary to use the others. There are a few simple conversions between them but first it is necessary to know their notation.
Cartesian:
Cylindrical:
Spherical:
In most [...]

Suppose you are interested in finding the unit vector between two points, and , which are described in cartesian coordinates as and , respectively.
You would begin by finding the vector between these two points. The direction of this vector may be important so look for key words such as . Once [...]

This is a very simple post and a very simple subject, but every once in a while even the experts need to be reminded how to do simple addition and subtraction with vectors. Let’s go ahead and specify a couple vectors that we can work with.
Vector
In MATLAB: >>A = [1 2 4];
Vector
In MATLAB: [...]
