31.2 Drawing Complex Numbers on a Plane: the Complex Plane
Point 2 of 4
31.2.2 A Complex Number Is Just an Arrow
Core idea
Picture this: the arrow pointing from the origin out to that point looks exactly like a vector from the last stage — that's the geometric identity of a complex number
Module goal. Borrowing the coordinate plane from the last stage, we give every complex number its own "address," turning it from a symbol into a visible point and arrow
