AI-generated Key Takeaways
-
The
tanh()method computes the hyperbolic tangent of a number. -
It takes a single numerical input and returns a numerical output.
-
The input value is typically interpreted as being in radians when calculating the hyperbolic tangent.
-
Examples are provided for both JavaScript and Python to demonstrate usage with various inputs, including converting degrees to radians before calculation.

// Input angle in radians. print ( 'Hyperbolic tangent of -5' , ee . Number ( - 5 ). tanh ()); // -0.999909204 print ( 'Hyperbolic tangent of -1' , ee . Number ( - 1 ). tanh ()); // -0.761594155 print ( 'Hyperbolic tangent of 0' , ee . Number ( 0 ). tanh ()); // 0 print ( 'Hyperbolic tangent of 1' , ee .

Number ( 5 ). tanh ()); // 0.999909204 // Convert degrees to radians. var degrees = 45 ; var radians = degrees * ( Math . PI / 180 ); print ( 'Hyperbolic tangent of 45 degrees' , ee . Number ( radians ). tanh ()); // 0.655794202
