         Actually Mathematica does something that makes more sense:
-            sage: mathematica.eval('Cos[x] + Sin[y] + x^2 + y^2 + t /. x^2 + y^2 -> t')
+            sage: mathematica.eval('Cos[x] + Sin[y] + x^2 + y^2 + t /. x^2 + y^2 -> t')       # optional -- requires mathematica
             2 t + Cos[x] + Sin[y]
