CMPLX 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 "R↔I" 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: (2ѿ3i)ѿ(4ѿ5i) ҃ 6ѿ8 i (Real part 6) (Imaginary part 8 i) 2 + 3 i + 4 + 5 i = A r E-7
