WinPlot is a mathematical tool, entirely in English, designed specifically for mathematicians and for all those mathematicians or students of Mathematics who do not know how to graph polar coordinates, or who need to generate two-dimensional or three-dimensional graphical representations of different functions or equations. Download WinPlot is basic for math students of any field; not surprisingly, it is a program that has been running since the time of Windows 95, and is still updated today with news and improvements, as its new interface to take advantage of the visual advantages of Windows 7.
With WinPlot you can generate and animate graphs of all kinds of functions, whether in two or three dimensions, from all kinds of equations: explicit, differential, parametric, etc. Thus, with WinPlot, in the graph you will be able to observe the behavior of each of the functions, and the form that each of the numerical values that it is taking are taking as they progress. WinPlot also offers online help to solve any problem you may have while using the program, with a great tutorial perfect to learn how to use the tools that WinPlot offers little by little.
Unfortunately, there is not yet a version of WinPlot in English, but since you can download WinPlot for free and use it for a lifetime, perhaps it would be a good way to contribute to the development of the application downloading the files to translate the WinPlot interface to English. You can do it from the author's page.
You can free download Winplot 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
