Previously Published Data 

1.) Determine whether the sum, difference, and product of complex numbers are real, imaginary or complex. 


2.) Recall the following: 
 
 
 

 
 
 
 
 
 
 

Evaluate and describe the pattern of i as its power changes from i to i(i)(i)(i)(i)(i)(i)(i)(i)(i). Show that i fits with the pattern. Determine what i(100), i(201) equals. 


3.) Model (-2 + 3i) + (1 - 4i) on a coordinate plane. 

Previously Published Data 

1.) Have students multiply various binomials that incorporate i. Make them use rationalization of complex numbers. (5 + 2i)(5 - 2i) (a + bi)(a - bi) 


2.) Simplify: 9 + 3i 2i 5 + i 1 + 2i
