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 |
---|---|
– [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)
- 30
