To obtain the conjugate complex number of 2 + 3 i (Complex number

format: a + b i )

12(CMPLX) 2(Conjg) 2 + 3 W(

i ) )= 2–3 i

To obtain the absolute value and argument of 1 + i Bv

Absolute Value: 1w(Abs) 1 +W(

i ) =

Argument: 12(CMPLX) 1(arg)1 +W( i ) )= 45

Using a Command to Specify the Calculation Result

Format

Either of two special commands ( 'r ∠  or 'a + b i ) can be input at the end

of a calculation to specify the display format of the calculation results. The

command overrides the calculator’s complex number format setting.

i = 2 ∠ 45, 2 ∠ 45 =

i Bv

! 2 e+! 2 eW(

i ) 12(CMPLX) 3( 'r ∠  ) = 2 ∠ 45

Using CALC

CALC lets you save calculation expressions that contain variables, which you

can then recall and execute in the COMP Mode ( N1) and the CMPLX

Mode ( N2). The following describes the types of expressions you can

save with CALC.

• Expressions: 2X + 3Y, 2AX + 3BY + C, A + B i

• Multi-statements: X + Y : X (X + Y)

• Equalities with a single variable on the left and an expression including

variables on the right: A = B + C, Y = X

+ X + 3

(Use Ss(=) to input the equals sign of the equality.)

To store 3A + B and then substitute the following values to perform

the calculation: (A, B) = (5, 10), (7, 20)

3 S-(A) +Se(B)

Prompts for input of a value for A Current value of A

5 = 10 =

s (or =)
