I really remember having to go through math and trigonometry under tutors that kept on pounding on your head that math was a neccesary nuisance, until I came across this remarkable book, I can tell you that it so clear and impressive that anyone, with or without mathematical background will be able to understand it. Remember that math is the universal language and for this book the piece by piece attack on the theme is more than enough to understand it, spanish is advisable though not essential, this book teaches you to love math and makes it fun, open and easy, it can be applied on your everyday life.
It takes you by the hand step by step from two variable equations to full scale three dimensional matrix series, giving it sense to a whole new world of mathematical thinking, right now I am going through a proccess to start my Masters by Research on Australia (On Biomedical Sciences), and to begin with I needed to refresh my memory on some algebra and trigonometry, I took some steps towards books like the Tippler and Shaums, and though they claim the easiness of use of its contents, to my surprise more that 80% percent of my answers were coming from the Baldor series.
Sometimes is easy to under estimate a book that comes from a neighboring country that is say "underdeveloped" but I think it is about high time that we might start to share some common knowledge that would enrich our mutual knowledege. By now I haven't found any book that comes closer to the comprehention that this book opens to the novele and experienced mathematician, I sincerely recomend this text to anyone that might be submerged into mathematic themes from shallow to deep, belive me it will not disappoint anyone, or at least it hasn't done so, I know more than a 100 people between students and serious proffessionals and investigators that have used it and are still using it. It has run water under the bridge since I used it and it is still brilliant and robust.
