The modulus and argument of complex numbers are really important. Here’s why:
Modulus: This tells you how big the complex number is. You can find the size by using this formula:
(|z| = \sqrt{a^2 + b^2})
In this formula, (z = a + bi).
Argument: This gives you the angle of the complex number on a graph called the complex plane. You can find the angle with this formula:
(\theta = \tan^{-1}(\frac{b}{a})).
When you use both the modulus and the argument together, they make it easier to see and work with complex numbers!
