Definition and UsageThe atanh() function returns the inverse hyperbolic tangent ratio of given given parameter. In other words, the return value of atanh() is hyperbolic tangent of given parameter. A inverse hyperbolic tangent function is defined as .atanh(x) = 0.5Xlog((1+x)/(1-x))This function returns a float value .Syntaxatanh ( float $arg ) ... Read More

Definition and UsageThe atan() function returns the arc tan or tan inverse of arg in radians. atan() is the inverse function of tan(). Therefore if tan(x)=y, atan(y)=x.For example, tan(pi/3)= 1.73205080757 (Squre Root of 3) and atan(1.73205080757)=1.04719755 rad which is equal to pi/3.This function returns a float value .Syntaxatan ( float ...
