TITLE: Can One use mathematica or maple online?
QUESTION [11 upvotes]: Is it possible to use some of these algebra packages online ?
I have some matrices that I would like to know the characteristic polynomial of.
Where could I send them to get a nicely factorised answer ?
My PC is very slow & it would be nice to use someone elses super powerful computer !
Any suggestions

REPLY [2 votes]: Next to Wolfram Alpha you can also try the Wolfram Cloud on  http://sandbox.open.wolframcloud.com, which allows you to enter and execute multiple Mathematica commands using an online Notebook document.
