Some students prefer not to use the sacred space of your hard drive, designed to save the media, to install programs in mathematics, the end of the day just finished the course what they want most is to forget everything smells like math.
For those who expect to have an application allowing them to easily see the graph of a function, there are two alternatives: one is to go to pages that have java plotter, you gets your role and will generate the chart, however I have not found a page that generates good graphics. The second option is highly recommended for those who use internet explorer junk, is to change browser, install Opera browser is a thousand times (or more) slower than Internet Explorer, the browser has the option to add widgets are applications running in the browser (in addition), some of these widgets are oriented to science and include one that can generate great 3D graphics easily. Try it you will not regret. There is also a widget that is a powerful scientific calculator and the other two-dimensional graphics functions (for calculation I).
PD (can add widget for mail, dictionaries, facebook and more. Really, if you only have internet explorer, I considered other alternatives to surf the internet, the best option is Mozilla, however Opera, Safari are also very good browsers, and of course a very well integrated with Google services is Chrome-all free.
Clarification: I have nothing against Microsoft, does not bother me that oblige us to use internet explorer as it comes integrated the OS, I just like Mozilla, I like to be free, its code is open, most supplements and the best are made by users and is a proven fact with serious analysis is a thousand times better than internet explorer. It even has a moral policy in the hands of people (the people) and freely giving valuable things occur, I also think Linux on Wikipedia, and the amount of free apps that are on the network. The intervention does all stupid, the world needs only a minimal regulatory bodies (more or less what Nozick, I suggest reading his book, "Anarchy, State and Utopia"), and let the world is as it should be "FREE.
