What will I learn?
The Complex Numbers Course gives you a fast, practical path to mastering a+bi, from core algebraic operations and common pitfalls to conjugates, modulus, and inverses. You will convert between rectangular, polar, and exponential forms, use Euler’s formula, and apply De Moivre’s Theorem to powers and roots. Visual work in the complex plane builds strong intuition for rotations, dilations, and geometric checks of your results.
