Hyperbolic Operations

Hyperbolic operations have properties that are very similar to the trigonometric operations described previously. However, the angle units setting does not affect the results of a hyperbolic function because these functions are not based on angles.


The Hyperbolic Key

The [ HYP ] key enables you to use the trigonometric keys on your calculator to perform hyperbolic functions. These [ INV ] key enables you to perform the inverse hyperbolic functions.

The following list shows the hyperbolic functions available on your calculator and the key sequences you use to obtain them. Note that the [ INV ] and [ HYP ] keys may be pressed in either order when calculating the inverse hyperbolic functions.

Hyperbolic Function : Key
Hyperbolic Sine : [ HYP ] [ SIN ]
Hyperbolic Cosine : [ HYP ] [ COS ]
Hyperbolic Tangent : [ HYP ] [ TAN ]
Inverse Hyperbolic Sine : [ HYP ] [ INV ] [ SIN ] or [ INV ] [ HYP ] [ SIN ]
Inverse Hyperbolic Cosine : [ HYP ] [ INV ] [ COS ] or [ INV ] [ HYP ] [ COS ]
Inverse Hyperbolic Tangent : [ HYP ] [ INV ] [ TAN ] or [ INV ] [ HYP ] [ TAN ]
