Computeralgebra notebooks / worksheets in Maxima 
The following Maxima notebooks (or "worksheets") are stored in the wxmx  format.  They can be downloaded and should be opened using the Open Source Maxima computeralgebra system (CAS)  with the wxMaxima frontend  (enabling the worksheet functions, modules or procedures to be evaluated interactively).  
Download site for Maxima / wxMaxima:  see e.g.   http://maxima.sourceforge.net/     
1.  Some historical algorithms
2.  Modeling and Simulation
