Description

This example illustrates plotting complex numbers in the fourth quadrant of the complex plane. The image shows four points: 1 - i, 5 - 3i, 2 - 8i, and 9 - 3i. These points represent complex numbers with positive real parts and negative imaginary parts.

Understanding how to plot complex numbers in all quadrants is essential for a comprehensive grasp of complex number theory. This example helps students visualize how complex numbers with positive real parts and negative imaginary parts are positioned on the complex plane.

By providing multiple examples of complex numbers in the fourth quadrant, students can develop a deeper understanding of the relationship between complex numbers and their geometric representation.

Teacher's Script: Look carefully at how these complex numbers are plotted in the fourth quadrant. Notice that the positive real part places the points to the right of the y-axis, while the negative imaginary part places them below the x-axis. Can you explain why these points are specifically in the fourth quadrant? Let's discuss how this relates to our understanding of both complex numbers and coordinate geometry.
