Chapter 15 - Real Number Systems"This chapter begins by reviewing the real number system and then move to introducing the imaginary and ultimately the complex number system. Using the powers of exponent rules, students discover the necessity of the number i. This discovery leads to students exploring whether quadratic functions have one, two, or no real roots" Carnegie Textbook |
