I don't seem to be able to get Mathematica 2.0.2 to integrate symbolically functions which are defined piecewise. A simplified example of what I'm trying to do is Mathematica 2.0 for NeXT Copyright 1988-91 Wolfram Research, Inc. -- NeXT graphics initialized -- In[1]:= f[x_] := x /; x <= 1 In[2]:= f[x_] := x^2 /; x >1 In[3]:= Integrate[f[x],x] Out[3]= Integrate[f[x], x] In[4]:= Integrate[f[x],{x,0,1}] Out[4]= Integrate[f[x], {x, 0, 1}] I've also tried defining f[x] using Switch[] but also with no success. Answers and/or suggestions will be most welcome. --- --------------------------------------------------------------------- Dave Rebnord drebnord at betenoir.syr.edu (NeXT) Dept of Mathematics drebnord at suvm.syr.edu (ascii) Syracuse University Syracuse NY 13244-1150
