# Mathematical Analysis IV A

## Objectives

The first chapters of the course are devoted to the complementary study of Ordinary Differencial Equations begun in Mathematical analysis III-A. the work of Cauchy, Liouville and others showed the importance of establishing general theorems to guarantee the existence of solutions to certain specific classes of differential equations. One of the chapters of our course is concerned with the proofs of some of these theorems. With respect to multiple integration, our study is intended to familiarize the student with the properties and with the methods of finding the values of doule and triple integrals. Our course also includes line integrals and surface integrals. These kind of integrals are of fundamental importance on both pure and applied mathematics. Finally we present two generalizations of the Green´s theorem, namely the Stokes theorem and the divergence theorem. The divergence theorem is useful in connection with the consideration of solid angles.
