Complex Number Calculations

kArithmetic Operations [OPTN]-[CPLX]-[i]

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

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

AK3(CPLX)

(b+c1(i))

+(c+d1(i))w

Example 2 (2 + i) ⋅ (2 – i)

AK3(CPLX)

(c+1(i))

*(c-1(i))w

kReciprocals, Square Roots, and Squares

Example (3 + i)

AK3(CPLX)

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

kComplex Number Format Using Polar Form

Example 2∠30 ⋅ 3∠45 = 6∠75

!m(SET UP)cccccc 1(Deg)c3(r∠θ)J

Ac!v(∠)da*d !v(∠)efw

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