In mathematics, a complex number is an element of a number system that contains the real numbers and a specific element denoted i, called the imaginary unit, and satisfying the equation \(i^2=−1\). This theorem can help us easily find the powers and roots of complex numbers in polar form, so we must learn about de moivre’s theorem.
