The Gross National Debt

National Debt and Wars
In this project you will collect information about the National debt, plot the data by decade, and determine whether an exponential curve is a good fit for the data. Then your groups will determine and compare common traits and differences in changes in the National debt in three major eras: the Civil War, World War I, and World War II.

2.4 - Complex Numbers
Objectives: Students will know how to perform operations with complex numbers and plot complex numbers in the complex plane.

Need to check your calculations?
The complex numbers applet does symbolic calcluations of complex numbers.

How are complex numbers related to polynomial functions?
This lesson explains the connection and includes an applet to help you visualize the connection
Connecting complex roots to a parabola's graph

Looking for more connections?
Understanding complex numbers are necessary to understand fractal geometry.
