This is termed the algebra of complex numbers. ematics of complex analysis. A number is real when the coefficient of i is zero and is imaginary when the real part is zero. Real analysis provides students with the basic concepts and approaches for internalizing and formulation of mathematical arguments. •Complex dynamics, e.g., the iconic Mandelbrot set.
