GEOMECA (Geometric Calculator) is a program that draws graphs and performs calculation as unique original software.
All pictures in this website were made by this software.
Please refer to 'catalog' or 'function, how to use' for more details.
The latest version 4.0
can draw graphs by expressions of functions, by using commands, by using the mouse with figure tools.
can draw a translated figure of an original graph by using translation.
draws 2- or 3-dimensional graphs and can draw bodies of rotation easily.
can make the effect of transparency, reflection, and shadow by using ray trace.
The position of the drawn graph of function can be traced point by point by trace function.
can do calculation in the range of rational numbers (the calculated result is represented to an irreducible fraction), real numbers, and complex numbers.
can calculate parametric multivariable expressions of funtions, (indefinite)integral , (partial)differential, matrix calculation, and statistic analysis.
+, -, *, /, sqr, decomposition to prime factors , nPr, nCr, nHr, n! can be calculated without regard to ciphers.
can write characters on the picture, open pictures, do basic editing of pictures.
The drawn graph can be collected and viewed and saved together, and modified later.
