Analysis I: Sequences and Series -- Dr Stewart -- 14 MT In these lectures we introduce the real and complex numbers and study their properties, particularly completeness; define and study limits of sequences, convergence of series, and power series. Real numbers: arithmetic, ordering, suprema, infima; the real numbers as a complete ordered field. The reals are uncountable. The complex number system. The triangle inequality. Sequences of real or complex numbers. Definition of a limit of a sequence of numbers. Limits and inequalities. The algebra of limits. Order notation: O, o. Subsequences; a proof that every subsequence of a convergent sequence converges to the same limit; bounded monotone sequences converge. Bolzano-Weierstrass Theorem. Limit point of a set. Cauchy's convergence principle. Series of real or complex numbers. Convergence of series. Simple examples to include geometric progressions and some power series. Absolute convergence, comparison test, ratio test, integral test. Alternating series test. Power series, radius of convergence; important examples to include the exponential, cosine and sine series.

Alternative reading The first five books take a slightly gentler approach to the material in the syllabus, whereas, the last two cover it in greater depth and contain some more advanced material.
