Abstract: |
Pointwise convergence. Uniform convergence. Uniform convergence and continuity - integrability - differentiability of the sum. The criterion of Weiertrass for uniform convergence. The criteria of Dirichlet and of Abel. Power series. Radius and interval of convergence of a power series. The theorem of Abel. Basic examples of power series: exponential, logarithmic, trigonometric, of the arc-tangent, binomial (with a thorough discussion about the interval of convergence and its endpoints). Taylor series. Basic examples of Taylor series: the previous examples but with the inverse course (from the function to the corresponding series). Thorough definition of the trigonometric functions: by means of the corresponding power serises. Proofs of the basic properties of the trigonometric functions.
(There is also a brief discussion of the definition by means of integrals: first of the arctangent and then of the sine and the cosine.) (In the previous chapters the trigonometric functions were taken for granted and they were used as examples for the application of relevant theorems.)
