Coordinate System Conversions 
There are three fundamental coordinate systems (rectangular, cylindrical, and spherical), each of which is a more
convenient means for calculations depending on the configuration of your model. For example, mapping points on the
surface of a sphere using the Cartesian coordinate system requires describing all three coordinates (x, y, and z)
in terms distance from each of the threes axis references. Doing the same in the spherical coordinate system
requires simply a radius and two angles. When you start doing very complex calculations like those requiring
calculus applications, choosing the best coordinate system can make the difference between nightmarish equations
and relatively simple ones.
Conversion formulas between the three fundamental coordinate systems are given below.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dialup modems blazed along at 14.4 kbps
while typing up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...
