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.
The following constants for the projection may be calculated :
B = {1 + [esq * cos^4(latc) / (1 - esq )]}^0.5
A = a * B * kc *(1 - esq )^0.5 / ( 1 - esq * sin^2(latc))
to = tan(pi/4 - latc/2) / ((1 - e*sin(latc)) / (1 + e*sin(latc)))^(e/2)
D = B (1 - esq)^0.5 / (cos(latc) * ( 1 - esq*sin^2(latc))^0.5)
if D < 1 to avoid problems with computation of F make D^2 = 1
F = D + (D^2 - 1)^0.5 * SIGN(latc)
H = F*(to)^B
G = (F - 1/F) / 2
gammao = asin(sin(alphac) / D)
lonO = lonc - (asin(G*tan(gammao))) / B
Forward case: To compute (E,N) from a given (lat,lon) :
t = tan(pi/4 - lat/2) / ((1 - e sin (lat)) / (1 + e sin (lat)))^(e/2)
Q = H / t^B
S = (Q - 1 / Q) / 2
T = (Q + 1 / Q) / 2
V = sin(B (lon - lonO))
U = (- V cos(gammao) + S sin(gammao)) / T
v = A ln((1 - U) / (1 + U)) / 2 B
u = A atan((S cos(gammao) + V sin(gammao)) / cos(B (lon - lonO))) / B
The rectified skew co-ordinates are then derived from:
E = v cos(gammac) + u sin(gammac) + FE
N = u cos(gammac) - v sin(gammac) + FN
Reverse case: Compute (lat,lon) from a given (E,N) :
v? = (E - FE) cos(gammac) - (N - FN) sin(gammac)
u? = (N - FN) cos(gammac) + (E - FE) sin(gammac)
Q? = e^- (B v ?/ A) where e is the base of natural logarithms.
S' = (Q? - 1 / Q?) / 2
T? = (Q? + 1 / Q?) / 2
V? = sin (B u? / A)
U? = (V? cos(gammac) + S? sin(gammac)) / T?
t? = (H / ((1 + U?) / (1 - U?))^0.5)^(1 / B)
chi = pi / 2 - 2 atan(t?)
lat = chi + sin(2chi).( e^2 / 2 + 5*e^4 / 24 + e^6 / 12 + 13*e^8 / 360) + sin(4*chi).( 7*e^4 /48 + 29*e^6 / 240 + 811*e8 / 11520) + sin(6chi).( 7*e^6 / 120 + 81*e8 / 1120) + sin(8chi).(4279 e^8 / 161280)

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.
