Die proses wat gevolg moet word om phi te bepaal is dieselfde as
dié om theta te bepaal, maar dit begin met 'n lyn wat loodreg is
met die VVPL. (Die O1X1-lyn in diagram 3.15 in Basson) Die lyn
wat op of af na die HVPL geteken word is 'n Z-waarde, (positief of
negatief) en dit ruil rigting oor O1X1.

The process that must be followed to determine phi is the same
as that to determine theta, but it begins with a line that is
perpendicular to the VPTL. (The O1X1 line in figure 3.15 of
Basson) The line drawn up or down to the HPTL is a Z-value,
(positive or negative) and it swaps direction over O1X1.
