When we have to measure the argument of a complex number then if we consider theta to be taken clockwise the angle is negative and if we consider taking it anticlockwise the angle is positive. But in case of a complex number the only information I have is which quadrant the number lies in, not it's direction. How can I then measure its argument? I've made many errors because of this confusion, can someone please explain to me in a video lesson?
