: Hyperbolic functions. Input a
function from the menu that appears when you press . The angle unit
setting does not affect calculations.
°,
ʳ
,
g
:
These functions specify the angle unit. ° specifies degrees,
ʳ
radians, and
g
grads. Input a function from the menu that appears when
you perform the following key operation:
.
: Exponential functions. Note that the input method is different
depending upon whether you are using Natural Display or Linear
Display.
log :
Logarithmic function. Use the
key to input Iog
a
b as log (a, b).
Base 10 is the default setting if you do not input anything for
a
. The
key also can be used for input, but only while Natural Display is
selected. In this case, you must input a value for the base.
