Mathematical background on errors

The picture of the light patches has been made in the following way:
x=x0 + h * ctg(altsun) * sin(azipas-azisun)

y=y0 + h * ctg(altsun) * cos(azipas-azisun)
Met: The errors in x and y are thus:
x=SQRT(|x0|^2 + 
    + |h * ctg(altsun) * sin(azipas-azisun)|^2 +
    + |altsun * h * sin(azipas-azisun) / sin2(altsun)|^2 +
    + |(azipasazisun) * h * cos(azipas-azisun) * ctg(altsun)|^2)  

y=SQRT(|y0|^2 +
    + |h * ctg(altsun) * cos(azipas-azisun)|^2 +
    + |altsun * h * cos(azipas-azisun) / sin2(altsun)|^2 +
    + |(azipasazisun) * h * sin(azipas-azisun) * ctg(altsun)|^2)
