acos (x)
Aliases: arccos
The arccos (inverse cos) function
acosh (x)
Aliases: arccosh
The arccosh (inverse cosh) function
acot (x)
Aliases: arccot
The arccot (inverse cot) function
acoth (x)
Aliases: arccoth
The arccoth (inverse coth) function
acsc (x)
Aliases: arccsc
The inverse cosecant function
acsch (x)
Aliases: arccsch
The inverse hyperbolic cosecant function
asec (x)
Aliases: arcsec
The inverse secant function
asech (x)
Aliases: arcsech
The inverse hyperbolic secant function
asin (x)
Aliases: arcsin
The arcsin (inverse sin) function
asinh (x)
Aliases: arcsinh
The arcsinh (inverse sinh) function
atan (x)
Aliases: arctan
Calculates the arctan (inverse tan) function.
See Mathworld for more information.
atanh (x)
Aliases: arctanh
The arctanh (inverse tanh) function
atan2 (y, x)
Aliases: arctan2
Calculates the arctan2 function. If x>0 then it returns atan(y/x). If x<0 then it returns sign(y) * (pi - atan(|y/x|). When x=0 it returns sign(y) * pi/2. atan2(0,0) returns 0 rather then failing.
