### 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)

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

hi GgiPunjab

welcome to the forum!

arccos(x) is the inverse function of sin(x) funtion

anoni, who are you talking to?
Oh wait, maybe they deleted their post.

### Re: Trig Functions

anonimnystefy, how is arccos the inverse of arcsin?

### Re: Trig Functions

no it isn't arccos(x) is inverse of cos(x).i'm sorry.
