The following shows the required key operations and the
values this calculator uses for pi (
π) and e:
π = 3.14159265358980 ( (π))
e = 2.71828181845904 (
( e))
Trigonometric and Inverse Trigonometric
Functions
The angle unit required by trigonometric and inverse
trigonometric functions is one specified as the calculator’s
default angle unit. Before performing a calculation, be sure to
specify the default angle unit you want to use. See “Specifying
the Default Angle Unit” for more information.
Example: sin 30 = 0.5, sin
-1
0.5 = 30
(sin
-1
)
Hyperbolic and Inverse Hyperbolic Functions
Pressing the
key displays a menu of functions. Press the
number key that corresponds to the function you want to input.
Example: sinh 1 = 1.175201194, cosh
-1
1 = 0
(sinh)
(cosh
-1
)
Converting an Input Value to the Calculator’s
Default Angle Unit
After inputting a value, press (DRG ►) to display the
angle unit specification menu shown below. Press the number
key that corresponds to the angle unit of the input value. The
calculator will automatically convert it to the calculator’s
default angle unit.
