Certain expressions or initial values may result in error without convergence of results. · If an expression does not include an equals sign (=), the SOLVE function produces a solution for expression = 0.

F 1 k Inputting Engineering Symbols COMP EQN CMPLX · Turning on engineering symbols makes it possible for you to use engineering symbols inside your calculations. E-5 · To turn engineering symbols on and off, press the F key a number of times until you reach the setup screen shown below. Disp 1 · Press 1. On the engineering symbol setting screen that appears, press the number key ( 1 or 2) that corresponds to the setting you want to use. 1(Eng ON): Engineering symbols on (indicated by "Eng" on the display) 2(Eng OFF): Engineering symbols off (no "Eng" indicator) · The following are the nine symbols that can be used when engineering symbols are turned on. To input this symbol: Perform this key operation: Ak k (kilo) M (Mega) AM G (Giga) Ag T (Tera) At m (milli) Am µ (micro) AN n (nano) An p (pico) Ap f (femto) Af Unit 103 106 109 1012 10­3 10­6 10­9 10­12 10­15 · For displayed values, the calculator selects the engineering symbol that makes the numeric part of the value fall within the range of 1 to 1000. · Engineering symbols cannot be used when inputting fractions. · Example: 9 Ö10 = 0. 9 m (milli) Eng F . . . . . 1(Disp) 1 9 \ 10 = 9 1 0. m 900. When engineering symbols are turned on, even standard (non-engineering) calculation results are displayed using engineering symbols. E-6 AP J 9 1 0. 9 m 900. Complex Number Calculations CMPLX Use the F key to enter the CMPLX Mode when you want to perform calculations that include complex numbers.

F 2 · The current angle unit setting (Deg, Rad, Gra) affects CMPLX Mode calculations. You can store an expression in CALC memory while in the CMPLX Mode. · Note that you can use variables A, B, C, and M only in the CMPLX Mode. Variables D, E, F, X, and Y are used by the calculator, which frequently changes their values. You should not use these variables in your expressions. · The indicator "RI" in the upper right corner of a calculation result display indicates a complex number result. Press A r to toggle the display between the real part and imaginary part of the result. · You can use the replay function in the CMPLX Mode. Since complex numbers are stored in replay memory in the CMPLX Mode, however, more memory than normal is used up. · Example: (2 3i) (4 5i) (Real part 6) (Imaginary part 8 i) 6 8i 2+3i+4+5i= Ar E-7 k Absolute Value and Argument Calculation Supposing the imaginary number expressed by the rectangular form z = a + bi is represented as a point in the Gaussian plane, you can determine the absolute value (r) and argument ( ) of the complex number.
