Press K3(COMPLEX) to display the complex calculation number menu, which contains the following items.

{i} ... {imaginary unit i input}

{Abs}/{Arg} ... obtains {absolute value}/{argument}

{Conjg} ... {obtains conjugate}

{ReP}/{ImP} ... {real}/{imaginary} part extraction

{'r}/{'a+bi} ... converts the result to {polar}/{rectangular} form

You can also use !a(i) in place of K3(COMPLEX)1(i).

Solutions obtained by the Real, a+bi and r modes are different for power root (x') calculations when x < 0 and y = m/n when n is an odd number.

Example: 3x'(– 8) = – 2 (Real)

=1 + 1.732050808i (a+bi)

=260 (r, Deg mode)

To input the “ ” operator into the polar coordinate expression (r), press !v().

kArithmetic Operations[OPTN]-[COMPLEX]-[i]

Arithmetic operations are the same as those you use for manual calculations. You can even use parentheses and memory.

Example

(1 + 2i) + (2 + 3i)

AK3(COMPLEX)

(b+c1(i))

+(c+d1(i))w

kReciprocals, Square Roots, and Squares

Example

(3 + i)

AK3(COMPLEX)

!x(')(d+1(i))w
