The ATAN2 function
returns the arctangent
of the specified x and y
coordinates.
ATANH
The ATANH function returns the inverse hyperbolic tangent of a number. Number must be
between –1 and 1 (excluding –1 and 1). The inverse hyperbolic tangent is the value in which
the hyperbolic tangent is number, so ATANH(TANH(number)) equals number.
=ATANH(number)
Notice the example in Figure 10.7 where the number equals .1 and the inverse hyperbolic of
the number from the ATANH function equals 0.1003 .
Any real number between –1 and 1.
