Hyperbolic, Trigonometric
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 |
|---|---|
![]() |
|
![]() |
|
![]() |
|
![]() (sin-1) |
|
![]() (cos-1) |
|
![]() (tan-1) |
|
Specify the Angle Unit on the SETTINGS menu before performing calculations.
Example: sin 30 = 12 (Angle Unit: Degree)
30
