Question

When a complex number z is written in its polar form, z = r(cosθ + isinθ), the non-negative number is called the ____ of z.

a) Real part
b) Imaginary part
c) Magnitude
d) Argument

Answer 1

The non-negative number in the polar form of a complex number is called the magnitude.

Step-by-step explanation:

When a complex number is written in its polar form, it can be expressed as z = r(cosθ + isinθ), where r is the non-negative number. This non-negative number is called the magnitude of z.
