In several scientific disciplines, one makes use of functions to describe phenomena or processes. For these, mathematics offers a number of utilities. For instance, with the use of different coordinate systems, these functions can be described efficiently. To see which objects these functions represent, VisuMath is developed. Evidently, the objects that can be visualized live in a 2- or 3-dimensional space. So VisuMath visualizes only curves and surfaces.
The program VisuMath combines high quality visual output with ease of use. It is developed especially for research and education and is therefore free of charge for these purposes. Within the program, one can switch between English and Dutch but other languages can be added if one is willing to do some effort. Click here for an explanation on how this can be achieved.
This part is used to draw graphics of curves in a plane. The curves can be described using a function of one variable, a parameter equation, a polar equation or an implicit equation. Also for functions of one variable the first and second derivative, the mean function and the Taylor expansion can be computed and visualized. Furthermore, there is the possibility to calculate integrals of continuous functions and to visualize the area, the upper sum, the lower sum and the Riemann sum.
This part is used to draw graphics of surfaces in a 3-dimensional space. The surfaces can be described by means of a function of two variables, a parameter equation, an implicit equation or using cylindrical or spherical coordinates. Also, there is the possibility to draw tubular shaped surfaces.
With this option, it is possible to find the general equation of a non-degenerate conic, after entering the necessary data. Also, the conic is drawn including the corresponding transformed axes.
With this option, it is possible to observe 3D-objects dynamically and also to change options on the fly.
With this option, it is possible to store the 3d-model in different interesting formats for export to other packages (such as graphical editors and 3d-authoring software).
With this button, one switches between the design environment and the VRML-environment. To see the model as VRML-model however in the VRML-environment, it must first be saved as VRML-file. This is done with the option Output 3D. Furthermore, the PC on which VisuMath is installed must be equipped with a VRML viewer, for example the Cortona VRML client (can be downloaded from the Internet from the coordinates www.parallelgraphics.com/products/cortona/).
