Proposition 1.2.7: Adding complex numbers geometrically |
For any complex numbers z and w you can find the sum z+w by attaching the vector w to the tip of the vector z and completing a paralellogram. The diagonal of that paralellogram is the vector z+w. |
You can easily verify this by writing z and w as vectors in R2.
Adding vectors z and w
Subtracting vectors z and w
