Question

hey guys, kinda confused about this one. Im not sure what he wants. the question is:

What is the square of 12/13 + 5/13 i? What does this say about angles?

Answer 1

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

Answer 2

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

Answer 3

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)
