Eigenmath DS is a free computer algebra system ported to Nintendo DS. The aim of this project is to have a free CAS comparable to commercial systems such as Texas Instruments or HP calculators. The GUI is made with Woopsi 0.3.
Features
- For math function graphs.
- Script mode.
- Text zoom.
- Natural result display.
- Functions menu.
- Natural result display two-dimensional mathematical form.
- Manipulation of mathematical expressions in symbolic form.
- Plotting graphs and parametric plots of functions in two dimensions.
- Simplification to the smallest possible expression.
- Solution of linear equations.
- Differentiation.
- Indefinite and definite integration, including multidimensional integrals.
- Matrix operations including products, inverses, etc.
User guide
If the results are too big to display in normal font size, press Start button or try the tty terminal mode.
For a large formula or a big matrix use the script mode, is less tedious correct the values.
The command clear, clear all previous operations, asignations, results and clear the graph area except the script mode.
There are two ways to use draw button.
Example 1:
draw(sin(x)) enter
Example 2:
sin(x) draw enter
Don't forget, there is special funtions for matrix operations like dot, inv.
For matirx operations isn't are equal a* b that dot(a,b) or a^-1 and inv(a).
