This is Part II of my personal study notes in advanced mathematics. It entails theoretical analysis, solved examples, and exercises on the following topics: 9. FUNCTIONS OF COMPLEX VARIABLE Introduction to complex numbers The real and imaginary parts of a complex number Modulus and Argument of a complex number Complex number as vectors Cartesian and Polar representation of complex numbers Pure Real and Imaginary numbers Representation of complex numbers on a Riemann Sphere Algebraic operations on complex numbers. Conformal Mapping Inverse Transformation Series of complex numbers Cauchy's Theorem Cauchy's Theorem of Residue Cauchy's Integral formula 10. THEORY OF PROBABILITY Mathematical definition of probability Exclusive events Independent events Rules governing probability of independent events Dependent events Binomial law of probability Random variables Discrete distribution Continuous distribution Joint distribution of several variables Expectation Parameters of a frequency distribution Sheppard's correction Binomial frequency distribution Stirling's formula for the approximation of factorials of large numbers Chekychef's Theorem Normal frequency distribution or Gaussian distribution Poission's distribution Law of large numbers Correlation Scatter diagram Standard error of the mean SEM 11.
