if I put your long_diff in my calculator and execute 1 / tan(long_diff)
I get exactly your 1206.xxx with long_diff = 0.0475 with degree setting.
When I execute your complete calculation with radiant setting I come to the same result. So how did you calulate your result? cot isn't 1/tan, as far as I know. cot is the reverse of tan, that's why they write tan^-1 on calculators.
Mathematics are helpful, sometimes,

Part of my code where I am getting different values is
enclosed below.
//All variables are of type double.
long_diff = fabs(lon1_deg - lon2_deg)/2.0; //Absolute
value
cot1 = 1/(tan((long_diff)/90 * pi/2));
//cot1 value when I compile thro CW -
1206.226660616226
with long_diff value 0.04749999999999943
//Calculator gives me 69111.712627 which is correct
b'cos I get the correct distance using this value.
Does anybody have any clue on this behaviour.
