Complex number to polar coordinate
WebPolar coordinates will help us understand complex numbers geometrically. On the one hand, the usual rectangular coordinates x and y specify a complex number z = x + yi by giving the distance x right and … Webexamine the complex plane which is used to plot complex numbers through the use of a real axis (horizontal) and an imaginary axis (vertical). A point (a,b) in the complex plane would be represented by the complex number z = a + bi. Example 1: Plot the following complex numbers in the complex plane. a.) -2 + i b.) 1 – 3i c.) 3 i. Solution:
