Using a Command to Specify the Calculation Result

Format

Either of two special commands ('r∠ or 'a+bi) 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

2 1-(∠) 45 12(CMPLX)4('a+bi)=

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

• 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 =)

7 = 20 =

To exit CALC: A
