Results obtained revealed that it is efficient, because the graphics generated shown the user a real and concrete vision based on the supplied information for the CEP on-line program. Finally, based on the results, a deeper study regarding some limitations presented by the tool must continue, like the size of the sample and review calculus of limits, which are not performed by the program.
