Overview
Complex numbers are a fundamental concept in mathematics, combining real and imaginary components to form a new number system. They are expressed in the form a + bi, where 'a' is the real part and 'bi' is the imaginary part. Understanding complex numbers is crucial for advanced studies in mathematic...
