    Where did you get arctan(1/0) from... also, it's undefined.

    I know, it's undefined, when the degree 90 or -90.

    to find the angle correctly you should draw it in complex plane

    I still don't understand why theta=arctan(1/0) made 90 degrees, when for me it is undefined...

    Remember: to find the angle correctly you should draw it
