Rationals and Radicals

Description

A complex number is a non-real number expressed in forms such as a + bi, r e^(iθ), or r cos(θ) + i r sin(θ). Examples include 2 + 5i, 12 e^(iπ/4), and 5 cos(60°) + i 5 sin(60°). Complex numbers extend the number system to include imaginary units, enabling solutions to equations like x² = -1.
