Unit1: complex number system (HonAlg)
Mrs STROLE・2 minutes read
The text discusses the real number system, including rational and irrational numbers, as well as the introduction of the imaginary number "i" leading to complex numbers. Higher-level math courses explore the complex number system, combining real and imaginary components to form examples like 2 + 7i and 4 - 3i.
Insights
- The real number system consists of rational and irrational numbers, with rational numbers further divided into integers, whole numbers, and natural numbers.
- The introduction of imaginary numbers, represented by "i" as the square root of -1, leads to the formation of complex numbers when combined with real numbers, expressed as a + bi, where "a" is the real component and "b" is the imaginary component.
