A complex number is a number that can be expressed in the form \\( a + bi \\), where: - \\( a \\) and \\( b \\) are real numbers, - \\( i \\) is the imaginary unit, defined as \\( i = \\sqrt\{-1\} \\). In this representation: - \\( a \\) is called the **real part** of the complex number, - \\( b \\) is called the **imaginary part** of the complex number.
