I could copy the example from the Sqlite documentation or you could just
look it up in the API description. You write your function, in this
case only a few lines of code, and bind it to Sqlite using the API.

But the question was "how"
Probably i am asking time after time stupid questions only - It is because my
english is not half good to orientate oneself easily in the documentation, so
quick summary in someones answer makes more than hours of reading docs.
Usualy i am asking if i understand not to some paragraph in docs.
Sometime it is enough to read it in other words.
(Something you consider as absolutely simple, may be difficult to understand,
not technicaly, but as english text, or easy to overlook.
If you feel my questions incommodious, please ignore it.
Thank You

Just add a sine function in the normal manner of adding a function. It
is very simple.

Hi Friends
Is there a possibility to have sin cos an acos, functions in sqlite?
How to write it in?
I really need it and i have fear, that sinus values table will be so slow
and so big for critical precission.
I will need to select coordinates which are laying in circle of known
center and radius.
Unfortunately at small time intervals and on a slow machine.
Thanks
Jakub
