Study Notes
Complex Numbers: Definition
- A complex number combines a real part and an imaginary part
- These numbers support addition, subtraction, multiplication, and division
Complex Numbers: Form
- Complex numbers adhere to the structure $a + bi$
- $a$ = real part
- $b$ = imaginary part
- $i$ = imaginary unit, where $i = \sqrt{-1}$
Complex Numbers: Example
- For the complex number $3 + 4i$
- The real part is 3
- The imaginary part is 4
Operations: Addition
-
Add the real parts and imaginary parts separately: $(a + bi) + (c + di) = (a + c) + (b + d)i$
-
Example
-
$(2 + 3i) + (4 + 5i) = (2 + 4) + (3 + 5)i = 6 + 8i$
Operations: Subtraction
-
Subtract real and imaginary parts separately: $(a + bi) - (c + di) = (a - c) + (b - d)i$
-
Example
-
$(5 + 6i) - (1 + 2i) = (5 - 1) + (6 - 2)i = 4 + 4i$
Operations: Multiplication
-
Apply the distributive property, noting that $i^2 = -1$
-
$(a + bi)(c + di) = (ac - bd) + (ad + bc)i$
-
Example
-
$(2 + 3i)(4 + 5i) = -7 + 22i$
Operations: Division
-
Multiply the numerator and denominator by the conjugate of the denominator
-
$\frac{a + bi}{c + di} = \frac{(ac + bd) + (bc - ad)i}{c^2 + d^2}$
-
Example
-
$\frac{2 + 3i}{4 + 5i} = \frac{23}{41} + \frac{2}{41}i$
Complex Conjugate
- The complex conjugate of $a + bi$ is $a - bi$
- Multiplying a complex number by its conjugate yields a real number: $(a + bi)(a - bi) = a^2 + b^2$
Complex Conjugate Example
- The conjugate of $3 + 4i$ is $3 - 4i$
- $(3 + 4i)(3 - 4i) = 25$
Absolute Value (Modulus)
- The absolute value of $a + bi$ is the distance from the origin to $(a, b)$ in the complex plane
- $|a + bi| = \sqrt{a^2 + b^2}$
Absolute Value Example
- $|3 + 4i| = 5$
