I'm looking for interactive applications that are for university topics (designed for windows) in mathematics only , preferably something that doesn't include programming languages to use because those confuse me.
I'm looking for Something where you can just input the data akin to 3D - Xplor math. Another good example would be Geomview where you view and manipulate three-dimensional objects: you use the mouse to rotate, translate, zoom in and out, and so on. However this is designed for Unix.
I've looked at programs like Matlab, mathematica , octave , maplesoft but those seem technical and suited for professionals with experience.
The topics I am referring to include: algebra and trigonometry , linear algebra , calculus , differential geometry , numerical methods, sampling theory and signal processing , matrix equations , optimization and computational geometry.
If you can't provide any suggestions , places to start to learn the more technical programs are welcomed.
