anonymous · Answer

I think it means the Argument of the Complex Number, which would be tan-1(5/12)

anonymous · Answer

um is that a specific definition? the word Argument of the complex number?

anonymous · Answer

Yes. The argument of a complex number is the angle it makes when a line is joined from that complex number to the origin on the Argand Plane. (A normal graph plane with the real part on the X Axis, and the Imaginary part on the Y axis)
