I have a related question, sort of the reverse. Normally,
integrate(sin(x)*sin(x/3)/x^2, x, 0,inf);
works fine, no principal value message. Except sometimes in Sage it
*does* give a principal error message (via an ECL library interface
only, not interacting in the terminal).
Can anyone think of what command or flag could have been set for that
integral to return that?
If there isn't (which I suspect), then it must be something we are
sending to ECL that messes with something. Thanks!
