Answer 1

Answer:

Step-by-step explanation:

Hii

Either Part Can Be Zero. So, a Complex Number has a real part and an imaginary part. But either part can be 0, so all Real Numbers and Imaginary Numbers are also Complex Numbers.

And if first eq and second eq May be equal than it from 0

Answer 2

this case, the complex number is the origin, so there is no unique ray, so no angle defined. In general, a complex number may be written z = r e i θ , where is real and non-negative, and is real as well. When it doesn't matter what is, because all values give.
