Trig Functions

hi all

before i post about the trig functions i would just like to notice that this thread doesn't have a sticky.

now for the trig functions:
First there are some well-known trig functions:
sin
cos
tan(tg)
cot(ctg)
and their inverse functions:
arcsin
arccos
arctan(arctg)
arccot(arcctg)
Then there are some less known:
sec
cosec(csc)
arcsec
arccosec(arccsc)
And there are the least known ones like:
versin(vers,ver)
vercosin
coversin(cvs)
covercosine
haversin
havercosin
hacoversin
hacovercosine(the trig function with the longest name)
exsec
excsc(excosec)
crd(with full name of chord)

Wiki link:http://en.wikipedia.org/wiki/List_of_tr … identities

EDIT:What i forgot to mention are the hyperbolic functions:
sinh,
cosh,
tanh,
coth,
sh,
csch.
