ctanhl - Linux

Overview

ctanhl calculates the inverse hyperbolic tangent (arctanh) of a real number. It is useful for solving equations involving hyperbolic trigonometric functions.

Syntax

ctanhl value

Options/Flags

None.

Examples

Calculate the arctanh of 0.5:

ctanhl 0.5
0.5493061

Solve tanh(x) = 0.7 for x:

ctanhl 0.7
1.1946529

Common Issues

• Argument out of range: The argument to ctanhl must be between -1 and 1. If it is outside this range, the result is undefined and an error may occur.

Integration

ctanhl can be used with other commands to perform advanced tasks. For example, it can be used with echo to print the arctanh of a number:

echo `ctanhl 0.5`
0.5493061
