Given z = 3 + i, w = 1 + 3.
a. find z + w, and graph z, w, and z + w on the same complex plane. explain what you discover if you draw line
segments from the origin to those points z, w, and z + w. then, draw line segments to conect w to z + w
and z + w to z.
b. find −w, and graph z, w, and z − w on the same complex plane. explain what you discover if you draw line
segments from the origin to those points z, w, and z − w. then, draw line segments to conect w to z − w
and z − w to z.
