There are some builtin functions and operations:
Arg(z)
: Argument of the complex numberConjg(z)
: Conjugate of the complex numberRe(z)
: Real componentIm(z)
: Imaginary component►r∠φ
Displays the result in polar form.►a+bi
: Displays the result in rectangular form.Abs(z)
: Returns the magnitude (modulus).(1 + i)^4 + (1 - i)^2 = -4 + 20i
The angle unit is DEG
, see Angle Units

to open Complex menu, then select the Arg
item
Type the expression 1+i
Conjugate(2+5i) = 2 - 5i
Press SHIFT
