## Conversions Between Cartesian, Cylindrical and Spherical Coordinates

TweetThe 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 [...]

## Unit Vector Between Two Points

TweetSuppose 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 we have established [...]
