For Projected Coordinate System NAD27 / Texas South Central
Parameters:
Ellipsoid Clarke 1866, a = 6378206.400 metres = 20925832.16 US survey feet
1/f = 294.97870
then e = 0.08227185 and e^2 = 0.00676866
First Standard Parallel 28°23'00"N = 0.49538262 rad
Second Standard Parallel 30°17'00"N = 0.52854388 rad
Latitude False Origin 27°50'00"N = 0.48578331 rad
Longitude False Origin 99°00'00"W = -1.72787596 rad
Easting at false origin 2000000.00 US survey feet
Northing at false origin 0.00 US survey feet
Forward calculation for:
Latitude 28°30'00.00"N = 0.49741884 rad
Longitude 96°00'00.00"W = -1.67551608 rad
first gives :
m1 = 0.88046050 m2 = 0.86428642
t = 0.59686306 tF = 0.60475101
t1 = 0.59823957 t2 = 0.57602212
n = 0.48991263 F = 2.31154807
r = 37565039.86 rF = 37807441.20
theta = 0.02565177
Then Easting E = 2963503.91 US survey feet
Northing N = 254759.80 US survey feet
Reverse calculation for same easting and northing first gives:
theta' = 0.025651765 r' = 37565039.86
t' = 0.59686306
Then Latitude = 28°30'00.000"N

Lambert Conic Conformal (2SP)
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.
To derive the projected Easting and Northing coordinates of a point with geographical coordinates (lat,lon) the formulas for the one standard parallel case are:
E = EF + r sin(theta)
N = NF + rF - r cos(theta)
where
m = cos(lat)/(1 - e^2 sin^2(lat))^0.5 for m1, lat1, and m2, lat2 where lat1 and lat2 are the latitudes of the standard parallels.
t = tan(pi/4 - lat/2)/[(1 - e sin(lat))/(1 + e sin(lat))]^(e/2) for t1, t2, tF and t using lat1, lat2, latF and lat respectively.
n = (loge(m1) - loge(m2))/(loge(t1) - loge(t2))
F = m1/(n t1^n)
r = a F t^n for rF and r, where rF is the radius of the parallel of latitude of the false origin.
theta = n(lon - lon0)
The reverse formulas to derive the latitude and longitude of a point from its Easting and Northing values are:
lat = pi/2 - 2arctan{t'[(1 - esin(lat))/(1 + esin(lat))]^(e/2)}
lon = theta'/n +lon0
where
r' = +/-[(E - EF)^2 + {rF - (N - NF)}^2]^0.5 , taking the sign of n
t' = (r'/(aF))^(1/n)
theta' = arctan [(E- EF)/(rF - (N- NF))]
and n, F, and rF are derived as for the forward calculation.
