tools on the internet is to head off to google.
Well, I was looking for a matrix (which is a mathematical object)
calculator the other day, and have stumbled upon this very useful
mathematics portal: http://wims.unice.fr/wims/.
I must admit that I have not yet visited all the portions of this website.
However, I can strongly recommend their different calculators.
Finding a good, free online calculator gets quite tricky once dealing
with tasks more complicated than adding or multiplying.
Their matrix calculator and matrix multiplier, for instance, are easy
to handle, nearly bug-free, and quite comprehensive.
In the site, you will find:
- Lessons and references on various topics.
- Online calculators and plotters : numbers, functions, matrices, curves, surfaces, etc.
- Interactive exercises of various styles and levels.
- Mathematical recreations : puzzles and games.
- Virtual classes and portals to manage scored student works.
- Misc. interactive documents.
Cheers!
