Es una guía indispensable para estudiantes y profesionales de ingeniería que deseen utilizar las matemáticas como herramienta en su trabajo. El libro aborda de manera rigurosa y respetuosa con la matemática formal conceptos y técnicas fundamentales para resolver problemas complejos en ingeniería. A lo largo de sus seis capítulos se cubren temas esenciales. El primer capítulo repasa los fundamentos necesarios en matemáticas para ingenieros. El segundo capítulo se enfoca en la modelización de sistemas y redes, especialmente en problemas transitorios y de estado estacionario. El tercer capítulo explora el uso de las series de Fourier en situaciones de periodicidad y fenómenos repetitivos. En el cuarto capítulo se analiza la aplicación de la transformada de Fourier en problemas de impulsos de onda en tiempo continuo. El quinto capítulo aborda señales de tiempo discreto o muestreadas, y su procesamiento con TDF. Finalmente, el sexto capítulo introduce la transformada Z y su aplicación en el análisis de datos muestreados. El presente libro no busca competir con textos de matemáticas generales, sino proporcionar un enfoque específico para su aplicación en ingeniería. Los temas y formulaciones son ampliados respetando la matemática formal y los teoremas desarrollados en torno a las grandes transformadas, útiles en ingeniería. Con su enfoque claro y riguroso, Matemáticas avanzadas aplicadas a la ingeniería se convierte en una valiosa herramienta para el desarrollo de los cursos de ingeniería de nivel superior.
In the history of mathematics there are many situations in which cal- lations were performed incorrectly for important practical applications. Let us look at some examples, the history of computing the number ? began in Egypt and Babylon about 2000 years BC, since then many mathematicians have calculated ? (e. g. , Archimedes, Ptolemy, Vi` ete, etc. ). The ?rst formula for computing decimal digits of ? was disc- ered by J. Machin (in 1706), who was the ?rst to correctly compute 100 digits of ?. Then many people used his method, e. g. , W. Shanks calculated ? with 707 digits (within 15 years), although due to mistakes only the ?rst 527 were correct. For the next examples, we can mention the history of computing the ?ne-structure constant ? (that was ?rst discovered by A. Sommerfeld), and the mathematical tables, exact - lutions, and formulas, published in many mathematical textbooks, were not veri?ed rigorously [25]. These errors could have a large e?ect on results obtained by engineers. But sometimes, the solution of such problems required such techn- ogy that was not available at that time. In modern mathematics there exist computers that can perform various mathematical operations for which humans are incapable. Therefore the computers can be used to verify the results obtained by humans, to discovery new results, to - provetheresultsthatahumancanobtainwithoutanytechnology. With respectto our example of computing?, we can mention that recently (in 2002) Y. Kanada, Y. Ushiro, H. Kuroda, and M.
This book presents mathematical tools to solve partial differential equations, typical of physical problems. It explains in a detailed manner the process of solving the problems that typically arise in the context of physics. Although there are a large number of textbooks on this topic, few go so deep into the topic. One of the original and unique features of this book is emphasis on the mathematical formulation of the problems, as well as the analysis of several alternative ways to solve them. Importantly, the book provides a graphical analysis of the results when appropriate. It describes a wide scope of the problems, with detailed solutions and the methods involved, ranging from cases in one to three dimensions, from Cartesian to polar, cylindrical, and spherical coordinates and includes properties and applications of the Fourier transform to solve partial differential equations.
