Effective indefinite integrals training using problems selected with resolution stepwise of graphical form and with mathematical formThe resolution of indefinite integrals is a primordial factor in any student. The main problems that are presented are not understanding the professor's explanation, not to see the information and the mechanical resolution of the problems that they tell us. To get it it is necessary to have a method of resolution of problems that is effective, simple, elegant and that it is based on scientific knowledge. (mind graph method)
