Dear Paulo: ......Original Message...... From: Paulo Moraes Ferreira [mailto:paulom at compos.com.br] To: mathgroup at smc.vnet.net Subject: [mg33749] [mg33737] Difference Equations How can i solve difference equations in mathematica. I am doing a master in economics. Does anyone give some instructions with example. ......end original message...... Yes, Mathematica can indeed solve difference equations. Look in the help browser under DiscreteMath or RSolve. There are many examples. For example: In[1]:= <<DiscreteMath`RSolve` In[2]:= RSolve[{a[n+1]==n a[n],a[1]==1},a[n],n] Out[2]= {{a[n] -> (1+n)!}} -- Curt Fischer Tokyo Institute of Technology Dept. of Bioengineering
