Reasoning this might happen is as follows: sage: f(x)=x^3+1 sage: f.derivative() x |--> 3*x^2 sage: f.integral() /Users/.../sage-4.6.2.alpha1/local/bin/sage-ipython:1: DeprecationWarning: Variable of integration should be specified explicitly. #!/usr/bin/env python x |--> 1/4*x^4 + x
Argument for this deprecation was that one could conceivably want an integral with respect to other variables. Personally, I find this silly in this case, but several - possibly including robertwb :) though I may not remember correctly - were emphatic that this was necessary. - kcrisman -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
