Greg,
Many math books and handbooks have tables of tangents; many pocket
calculators will calculate them, and computer spreadsheet programs usually
can calculate them also. The cotangent is the reciprocal of (that is, one
divided by) the tangent. Also, the cotangent of an angle equals the
tange

I am new to the sundial list and am building a sundial based on an
example in Albert Waugh's book Sunidals Their Theory and Construction.
My problem is in computing lines of declination, however. I live in
Washingotn DC at approx. 39d West Lat. 77d N Long. I'd like to trace the
sun's path for one
