complex number<\/a> is represented by the point, or by the vector from the origin to the point.<\/p>\n<\/p>\n
Add 3 + 4i and -4 + 2i graphically.<\/p>\n
Graph the two complex numbers 3 + 4i and -4 + 2i as vectors.<\/p>\n
Create a parallelogram using these two vectors as adjacent sides.<\/p>\n
The answer to the addition is the vector forming the diagonal of the parallelogram (read from the origin).<\/p>\n
This new vector is called the resultant vector.<\/p>\n

Subtract 3 + 4i from -2 + 2i<\/p>\n
Subtraction is the process of adding the additive inverse.
\n(-2 + 2i) – (3 + 4i)
\n= (-2 + 2i) + (-3 – 4i)
\n= (-5 – 2i)<\/p>\n
Graph the two complex numbers as vectors.<\/p>\n
Graph the additive inverse of the number being subtracted.<\/p>\n
Create a parallelogram using the first number and the additive inverse. The answer is the vector forming the diagonal of the parallelogram.<\/p>\n

Representing Complex Numbers Graphically (+ &\u00a0-) Due to their unique nature, complex numbers cannot be represented on a normal set of coordinate axes. In 1806, J. R. Argand developed a method for displaying complex numbers graphically as a point in a coordinate plane. His method, called the Argand diagram, establishes a relationship between the x-axis […]<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_genesis_hide_title":false,"_genesis_hide_breadcrumbs":false,"_genesis_hide_singular_image":false,"_genesis_hide_footer_widgets":false,"_genesis_custom_body_class":"","_genesis_custom_post_class":"","_genesis_layout":"","footnotes":""},"categories":[5],"tags":[3077],"yoast_head":"\n
