## Complex Number Tutorial

Complex Number is interesting because it unites many fields of mathematics such as Number Theory, Algebra, Euclidean and Polar Geometry, Trigonometry and Vector algebra, Function transformation and Fractal geometry. Complex number is useful for many engineering applications including transfer function of control theory and Fourier Transform, which in turn is one the most useful technique in digital image processing, signal processing, time series analysis and so on just to name a few.
