Casio fx-3650P II - Scientific Function Calculations: Advanced Functions; Angle Unit Conversion; Hyperbolic and Logarithmic;Exponential Functions

E-18
A
Notes
• These functions can be used in the CMPLX Mode, as long as a complex number is not
used in the argument. A calculation like
i
× sin(30) is supported for example, but sin(1 +
i
)
is not.
• The angle unit you need to use in a calculation is the one that is currently selected as the
default angle unit.

Angle Unit Conversion
You can convert a value that was input using one angle unit to another angle unit.
After you input a value, press
1G
(DRG
'
) to display the menu screen shown below.

Notes
• After pressing
w
to specify a hyperbolic function or
1w
to specify an inverse
hyperbolic function, press
s
,
c
, or
t
.
• These functions can be used in the CMPLX Mode, but complex number arguments are
not supported.
