As professor of Mathematics, I have taught Applied Statistics, Calculus, Differential Equations for more than 15 years; I have the habit of preparing my own notes, so I have enough material at the moment. At the moment I do not give classes in the University; the motivation to create this blog is to share my class notes, so the writing effort, which is many hours, can help students, otherwise would be lost, and I continue to collaborate with the true protagonists of the University: the students.

Class notes include exercises and problems, originally in Spanish, it took me a few years, in my free time, to pass all the material to the web format. The next project is publish the English translate, and also to add other resources, such as some specific video classes, or Moodle self-assessment questionnaires.
