Thank you for your contributions to increase our knowledge base here.
I just have a couple of comments:
a) I highly recommend that you learn to use $\LaTeX$. It makes such posts much easier to read, and there is a certain amount of satisfaction gained from using it to make nice looking posts. There are tutorials here and online to get you started, and we have a sub-forum here dedicated to the use of $\LaTeX$ in which you can ask questions.
b) While we have an international membership, many of our members do not read Spanish, and we ask that information be given in English, as this is the language of choice here. Thus, contributions to our forums should be made in English, otherwise the ultimate goal of the community ‒ which is, precisely, to be a community ‒ will be lost.
Petrus was not creating a tutorial topic, which we hold to higher standards. He simply created a rough sketch which sufficed for the purpose of getting his question answered....
the user petrus with the topic The double rectangle is full of f over R and midpoint rule for double integrals and drawings are not good, not for who are poorly made if not for that look ugly....
I just think if any contribution That'll do better with commentary in English and that I try to do all written in English on that I'm going to improve, and if I can in latex, but I think you have some pictures or symbol invented by me, and I handle some staff notation and mine own symbolism in latex do not think you can do the same ..... thanks for your comments and for your criticism,,,,,,

hello ....... MarkFL wanted to ask in this exercise that I not included the other sheet where I resolved scanned electric charge point at time t, if I scan this one could include in the photos that I gave to principle for the exercise remains continuous all the consecutive sheets, or conversely if I scanned would remain as a separate attachment to what I already I solved the circuit.Hello,
I have moved this post to the commentary thread. The other posts were left because they predate the creation of the commentary thread. We ask that when a tutorial topic is created, a commentary topic is also created, this way comments can be made, but the original tutorial topic is not cluttered with these comments.

The mathematics can be done using $\LaTeX$ and supporting diagrams can be attached. How you decide to create the diagrams is up to you.
I have no pictures/symbols invented by you...I'm not sure what you mean by this or that I cannot do the same.
I also recommend if you are going to create tutorial topics, it is best to solve the problem in as general a way as possible, and only then, once the theory has been developed, apply it to specific problems. This is more instructive.
