Limits MIT..18.02

          Within this second class is able to learn the concept of limit and continuity, and Prof. David Jerison same address several examples so that students gain a better understanding of both concepts.

The development of the class was very good, since the beginning teacher recalling seen in the previous class, and it started with the new issues now would be limits and continuity, what I call the exchange rate as an interpretation of the derivative .

            Something I think is important to note is that I'm always looking to bring the calculation to what the real world, because even though student participation was low, the development is very good, eh did the imagination in this session.

I mention about the Halloween event, or more commonly the pumpkin drop, where with small equations simplifies this fact, it is a clear example of calculation in the world today. 

           Defined the term continuity which is, that for which, intuitively, for points near the domain are small changes in the values ​​of the function. If the function is not continuous, is said to be discontinuous. Usually a continuous function is one whose graph can be drawn without lifting the pencil from the paper. If the function is continuous, not discontinuous, and himself gave the famous conclusion that every differentiable function is continuous, but not every continuous function is differentiable.

            Easy to speak of the limits and the limits are not so easy, those of the form: 1 / X ... When X tends to 0 ..

To cite an example of the limits is not so easy.
With his words mentioned about term limits, saying that is the outline or approach by both right or left of a point on the line. I speak the words: infinite discontinuity removable discontinuity.

             No doubt that the class was very good, and it is a great contribution of MIT, offer these videos on the net, for the world and free, it motivates and encourages us more to learn this important language such as English.

Homework; creating my little song !!

In life there are times when you feel sad,
and in your mind insecurity seem to take control,
do not be afraid to find the waylooking inside yourself and finding the strength to guide your destiny.

CELLULAR TECHNOLOGY !!

          Android is a Linux-based operating system for mobile devices such as smartphones or tablets. Was originally developed by Android Inc., a firm bought by Google in 2005

Android has a large community of developers writing applications to extend the functionality of the devices.

          The announcement of Android was held November 5, 2007 along with the creation of the Open Handset Alliance, a consortium of 78 hardware companies, software and telecommunications dedicated to developing open standards for mobile devices. Google released the Android code mostly under the Apache License, a free license and open source.

          Androi seems to be a success because your broadband from 4Gb. is already a great advantage, besides the call, and voice search on google.
Its cost is still high, but with time and as demand grows up will have to lower its price.

GALAXY ANDROID !!

TABLET PC

A tablet PC is a laptop with which you can interact via a touch screen or multi. The user can use a pen stylus or finger to operate the computer without a physical keyboard or mouse.

Some of their uses include:
Reading eBooks
Reading comics on screen
Web browsing
Games
Consultation office documents
Watching videos / movies
Playing Music
Videoconferencing

Undoubtedly, this technology already saw coming, it already years ago cell phones were used touch, and some other devices, then just enough PC, profits are diverse and helpful, and as expected this PC are still in a high price, began his rise as tools, but once well established and more demand will tend to lower its price, and all or most will have access to such technology.

And then an image of this type of technology, TABLET PC.

Augmented Reality !!

          Augmented reality (AR) is the term used to define a vision of a direct or indirect physical environment of the real world, the elements are combined with virtual elements to create a real-time mixed reality. It consists of a set of devices that add virtual information to the existing physical information, ie adding some synthetic virtual reality. This is the main difference with virtual reality, since it does not replace the physical reality, but superimposes computer data to the real world.

The augmented reality offers many new possibilities of interaction that are to be present in many and various fields such as architecture, entertainment, education, art, medicine or virt ual communities.

Applications
* Educational projects, surgery, simulation, architecture, advertising, tourism, among others.

          This application has had its heyday in early 2010 and to date, given that applications have given good, personally the first time I saw him was in the Filsol festival in the city of Chilpancingo, because there we gave a short talk on these issues, the speakers were students of mathematics ... and really good I found the talk, as are current issues of how this technology today.

J CLIC !!

         JClic is an environment for the creation, implementation and evaluation of educational activities developed in the Java programming language. Is a free software application based on open standards operating in different operating environments: Linux, Mac OS X, Windows and Solaris.

 

 The objectives at the start of the project are:

 

 *To enable the use of multimedia educational applications on-line directly from the Internet.

*Maintain compatibility with existing applications Clic 3.0.

 *Enable their use in various platforms and operating systems including Windows, GNU / Linux, Solaris or Mac OS X.

 *Using a standard open format for storing data, to make them transparent to other applications and facilitate their integration into database resources.

 *Expanding the scope of cooperation and exchange of materials between schools and educators from different countries and cultures, promoting the translation and adaptation of both the program and the activities created.

 *Collect suggestions for improvements and expansions that users have been sending.  

*To enable the program to be expanded from the cooperative work between different programming teams.

*Creating an environment to create more powerful activities, simple and intuitive, adapting to the characteristics of current graphical user environments.

*The programming tool Java has been chosen, and the format to store the activity data is XML.

 Jclic In my opinion, is a good tool to enhance creativity in children, because it is true that our math area such programs are useful.

 

 

 

brief account of the rock band U2 !!

          Paul David Hewson, OBE, better known by his stage name Bono (Dublin, May 10, 1960) is an Irish musician, member of rock band U2 and political activist, especially committed to the humanitarian cause in Africa and for cancellation of external debt of Third World countries, a task known among others for consecutive nominations to the Nobel Peace Prize in 2005 and 2006.

          Rock band U2 have a tour of 360 °, in Mexico took place on 11 May, the consumer event at the Azteca Stadium, and offered 3 gigs worth mentioning that according to figures on the Internet, Mexico ranks 3rd . place in sales followed by Sao Paulo and Dublin, the latter his hometown of singer Bono.http://en.wikipedia.org/wiki/U2_360%C2%B0_Tour

U2 is one of the rock bands that even though the years continue to maintain life and prestige



Fundamental Theorem of Calculus !!

          The fundamental theorem of calculus is (intuitively) in the claim that the derivation and integration are inverse operations function. This means that any continuous integrable function verifies that the derivative of its integral is equal to itself. This theorem is central to the branch of mathematics called mathematical analysis or calculus.

          The theorem is essential because until then the estimate of area-integral-which had been working since Archimedes was a branch of mathematics that is still separate differential calculus that had been developed by Isaac Newton, Isaac Barrow and Gottfried Leibniz in the eighteenth century and led to concepts such as derivatives. The integrals were investigated as ways to study areas and volumes, until this point in history both branches converged, the study demonstrated that the "area under a function" was intimately connected to differential calculus, resulting in the integration, the inverse operation referral.

         A direct consequence of this theorem is the rule of Barrow, sometimes called the second fundamental theorem of calculus, which calculates the integral of a function using the indefinite integral of the function to be integrated.

In all areas of mathematics there fundamental theorems, which are the core of some mathematical branch, so the same as a simple comment, the calculation has three funadamntales concepts, which are set, functions and limitations.
And it is from them that is based on calculation for better study and cocepción, because all three are vastly larger and a great contribution to mathematics.
