/*
 * all subFns are local to this file so they need not be renamed to
 * the awful 7 letter standard; however, for reasons of uniformity,
 * they are being renamed, losing all readability in the process.
 * the renaming convention is as follows: 
 *   example: 3v3F1m2
 * 3v => 3 variable term xyz
 * 2F1m2 => Two F1 minus F2
 * therefore the old name would be : S3v3F1minusF2
 * for the imaginary sub functions, the v is replaced by an i
