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 =
1
