Definicja wiek 18 lat poziom 3
For a real number z, the modulus is the absolute value.
For a complex number z=x+iy, the modulus is x2+y2 or z [(z)] .
In either case the notation - z - is used for the modulus of z; it is the distance of z from zero.
|z1−z2| gives the distance between two complex numbers.
