[. . . ] To perform prime factorization on 4104676 (= 22 (FACT) Any one of the following operations will exit prime factorization result display. · Pressing any of the following keys: or . · Using the setup menu to change the angle unit setting (Deg, Rad, Gra) or the display digits setting (Fix, Sci, Norm). Note: · You will not be able to execute prime factorization while a decimal value, fraction, or negative value calculation result is displayed. Trying to do so will cause a math error (Math ERROR). · You will not be able to execute prime factorization while the result of a calculation that uses Pol, Rec is displayed. 10132) E-13 C Function Calculations For actual operations using each function, see the "Examples" section following the list below. : is displayed as 3. 141592654, but internal calculations. sin, cos, tan, sin-1, cos-1, tan-1 : Trigonometric functions. Specify the angle unit before performing calculations. sinh, cosh, tanh, sinh-1, cosh-1, tanh-1 : 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: (DRG ). Note that the input method is different depending upon whether you are using Natural Display or Linear Display. Use the key also 10 is the default setting if you do not input anything for a. The can be used for input, but only while Natural Display is selected. In this case, you must input a value for the base. See 6. = 3. 14159265358980 is used for e : e is displayed as 2. 718281828, but e = 2. 71828182845904 is used for , , , x-1 : Powers, power roots, and reciprocals. Note that , , and are different depending upon the input methods for x , whether you are using Natural Display or Linear Display. [. . . ] Initialize all modes and settings by performing the following operation: (CLR) (Setup) (Yes). Replacing the Battery A low battery is indicated by a dim display, even if contrast is adjusted, or by failure of figures to appear on the display immediately after you turn on the calculator. If this happens, replace the battery with a new one. Important: Removing the battery will cause all of the calculator's memory contents to be deleted. · To ensure that you do not accidentally turn on power while replacing the battery, slide the hard case onto the front of the calculator (fx-85ES PLUS).
