### 6.10.5 The normalized complex number: normalize unitV

The normalize command finds the unit complex number with the same direction as a given complex number.
unitV is a synonym for normalize.

- normalize takes one argument:
  z, a non-zero complex number.
- normalize(z) returns the unit complex number with the same direction as z, namely z divided by the modulus of z.

Example.
