1 R = sin a 1 x + cos a sin b 1 y + cos a cos b 1 z ,
cos θ = cos a cos b .
h = f [ θ ] ,
f [ θ ] = f θ .
tan ϕ = sin b / tan a ;
x = h cos ϕ ;
y = h sin ϕ .
r = ( x 2 + y 2 ) 1 / 2 ;
g = r / tan f - 1 [ r ] ,
a = arctan [ x / ( g 2 + y 2 ) 1 / 2 ] ,
b = arctan ( y / g ) ,
f - 1 [ r ] = R + p R 3 + q R 5 .
