Document Summary

Provide a generalization to each of the key terms listed in this section. While noted as i, is the given number whose square is going to be 1, which notes that: i2 = 1. Numbers that occur in the form of a ratio. Numbers that would not occur in the form of a ratio. Any numbers that are in the form of where the following occur: a and b are real numbers, z is the standard form. B is the imaginary part: i is the imaginary unit. So this notes that z = a + bi i2 = i i = 1. Adding, subtracting, multiplying, and dividing complex num- bers. If and only if a = c and b = d a + bi = c + di. Sum of complex numbers (a + bi) + (c + di) = (a + c) + (b + d) i.
