ATANH(z)

• where z is any number between -1 and 1.

Description

• This function gives the Inverse Hyperbolic Tangent of a number.
• Here 'z' is any number between -1 and 1. ie $-1<z<1$
• Inverse Hyperbolic Tangent of a number is defined by $Atanh(z)={\frac {1}{2}}\log _{e}({\frac {1+z}{1-z}})$
• TANH(-z)=-TANH(z). Also ATANH(TANH(z))=z
• ATANH(1)=Infinty

Examples

ATANH(z)

• z is any real number between -1 & 1.

ATANH(z)	Value
ATANH(0.1)	0.100353477
ATANH(0.75)	0.97295507
ATANH(-0.3)	0.309519604
