sin, cos, tan, sin−1, cos−1, tan−1 : Trigonometric functions. Specify the angle unit before performing calculations. See 
1.
sinh, cosh, tanh, sinh−1, cosh−1, tanh−1 : Hyperbolic functions. Input a function from the menu that appears when you press w. The angle unit setting does not affect calculations. See 
2.
°, 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: 1G(DRG'). See 
3.
$, %: Exponential functions. Note that the input method is different depending upon whether you are using Natural Display or Linear Display. See 
4.
log: Logarithmic function. Use the l key to input logab 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. See 
5.
ln: Natural logarithm to base e. See 
6.
x2, x3, x^, ), #, ", x−1 : Powers, power roots, and reciprocals. Note that the input methods for x^, ), #, and "are different depending upon whether you are using Natural Display or Linear Display. See 
7.
Note: The following functions cannot be input in consecutive sequence: x2, x3, x^, x−1. If you input 2ww, for example, the final w will be ignored. To input 222 , input 2w, press the d key, and then press w(B).
Pol, Rec : Pol converts rectangular coordinates to polar coordinates, while Rec converts polar coordinates to rectangular coordinates. See 
8.

Rnd : The argument of this function is made a decimal value and then rounded in accordance with the current number of display digits setting (Norm, Fix, or Sci). With Norm 1 or Norm 2, the argument is rounded off to 10 digits. With Fix and Sci, the argument is rounded off to the specified digit. When Fix 3 is the display digits setting, for example, the result of 10 ÷ 3 is displayed as 3.333, while the calculator maintains a value of 3.33333333333333 (15 digits) internally for calculation.
