When a complex number is written in its polar form, z=r(cos theta + i sin theta) , the angle theta is called the "argument" of z. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

when the complex number is written in its polar form, the angle  is called the argument of z.

Step-by-step explanation:

An argument of the complex number z = x + iy, denoted arg(z), is defined in two same ways:

1.Geometrically, in the complex plane, as the angle   from the positive real axis to the vector representing z. The numeric value is given by the angle in radians and is positive if measured counterclockwise.

2. Algebraically, as any real quantity such that

So, when the complex number is written in its polar form, the angle  is called the argument of z.

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.

hope i could ! : )
