a = 6378137.0 metres 1/f = 298.2572236
then e = 0.081819191
Latitude of standard parallel (latF): 71°00'00.000"S = -1.239183769 rad

False easting (FE): 6000000.00 metres
False northing (FN): 6000000.00 metres
Forward calculation for:
Latitude (lat) = 75°00'00.000"S = -1.308996939 rad
Longitude(lon) = 120°00'00.000"E = 2.094395102 rad

mF = 0.326546781
ko = 0.97276901
t = 0.132508348
pho = 1638783.238
whence
E = 7255380.79 m
N = 7053389.56 m
Reverse calculation for the same Easting and Northing (7255380.79 E, 7053389.56 N) first gives:
tF = 0.168407325 mF = 0.326546781 and ko = 0.97276901
then rho' = 1638783.236 t' = 0.132508347 chi = -1.3073146
Then Latitude (lat) = 75°00'00.000"S

Polar Stereographic (variant B)
Note: These formulas have been transcribed from EPSG Guidance Note #7-2. Users are encouraged to use that document rather than the text which follows as reference because limitations in the transcription will be avoided.
First calculate the scale factor at natural origin:
for the south pole case
tF = tan (pi/4 + latF/2) / {[(1 + e sin(latF)) / (1 ? e sin(latF))]^(e/2)}
but for the north pole case
tF = tan (pi/4 - latF/2) * {[(1 + e sin(latF)) / (1 ? e sin(latF))]^(e/2)}
then for both cases
mF = cos(latF) / (1 ? e^2 sin^2(latF))^0.5
ko = mF {[(1+e)^(1+e) (1?e)^(1?e)]0.5} / (2 tF)
The forward and reverse conversions then follow the formulae for the
Polar Stereographic (variant A) method:
For the forward conversion from latitude and longitude, for the south pole case
E = FE + rho * sin(lon ? lonO)
N = FN + rho * cos(lon ? lonO)
where
t = tan(pi/4 + lat/2) / {[(1 + e sin(lat)) / (1 ? e sin(lat))]^(e/2)}
rho = 2*a*ko*t / {[(1+e)^(1+e) (1?e)^(1?e)]^0.5}
For the north pole case,
rho and E are found as for the south pole case but
t = tan(pi/4 ? lat/2) * {[(1 + e sin(lat)) / (1 ? e sin(lat))]^(e/2)}
N = FN ? rho * cos(lon ? lonO)
For the reverse conversion from easting and northing to latitude and longitude,
lat = chi + (e^2/2 + 5e^4/24 + e^6/12 + 13e^8/360) sin(2 chi)
+ (7e^4/48 + 29e^6/240 + 811e^8/11520) sin(4 chi)
+ (7e^6/120 + 81e^8/1120) sin(6 chi) + (4279e^8/161280) sin(8 chi)
where rho' = [(E-FE)^2 + (N ? FN)^2]^0.5
t' =rho' {[(1+e)^(1+e) * (1? e)^(1-e)]^0.5} / (2 a ko)
and for the south pole case
chi = 2 atan(t' ) ? pi/2
but for the north pole case
chi = pi/2 - 2 atan t'
Then for for both north and south cases if E = FE, lon = lonO
else for the south pole case
lon = lonO + atan2[(E ? FE),(N ? FN)]
and for the north pole case
lon = lonO + atan2[(E ? FE),(FN ? N)]

Since the natural origin may be at or near the centre of the projection and under normal coordinate circumstances would thus give rise to negative coordinates over parts of the mapped area, this origin is usually given false coordinates which are large enough to avoid this inconvenience. The False Easting, FE, is the value assigned to the abscissa (east or west) axis of the projection grid at the natural origin.
