# Thread: The Argument Of Z

1. ## The Argument Of Z

Hi this is my first time doind Arg and i dont know the method for solving this question, which is making me really frustrated.

The question says:
Find the Argument of z for each of the following in the interval [2,2pi]

A) Z=1-√3i

B) Z=-√7

C) Z=55

D) -2-2√3i

can you guys please answear them i got like a whole 10 questions on this, and 1 more **thing** when it says tan-1 is restricted to (–90°, 90°) or does that mean it goes from 90 to 180 clockwise or like its the right hand side of the unit circle.

thnx pleeaseee help

thnx

Draw each point on an Argand diagram. Apply the definition of Argument and use trigonometry.
