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∠Ƨ}/{'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∠Ƨ 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) = 2∠60 (r∠Ƨ, Deg mode) • To input the " ∠ " operator into the polar coordinate expression (r∠Ƨ), press !v(∠). k Arithmetic 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 k Reciprocals, Square Roots, and Squares Example (3 + i) AK3(COMPLEX) !x(')(d+1(i))w 2-35
