This section explains hyperbolic and trigonometric functions.

Hyperbolic Functions

Hyperbolic functions can be input using the menu items below.

– [Hyperbolic/Trig] > [sinh], [cosh], [tanh], [sinh-1], [cosh-1], or [tanh-1]


The angle unit setting does not affect calculations.


Example: sinh 1 = 1.175201194

  • – [Hyperbolic/Trig] > [sinh] 1

Trigonometric Functions

Trigonometric functions can be input using the keys or menu items below.

Key Menu Item

– [Hyperbolic/Trig] > [sin]

– [Hyperbolic/Trig] > [cos]

– [Hyperbolic/Trig] > [tan]
(sin-1)

– [Hyperbolic/Trig] > [sin-1]
(cos-1)

– [Hyperbolic/Trig] > [cos-1]
(tan-1)

– [Hyperbolic/Trig] > [tan-1]

Specify the Angle Unit on the SETTINGS menu before performing calculations.


Example: sin 30 = 12 (Angle Unit: Degree)
