The new forums will be named Coin Return (based on the most recent vote)! You can check on the status and timeline of the transition to the new forums here.
The Guiding Principles and New Rules document is now in effect.
I don't recall ever running into it, but given that it comes up in fourier stuff and is merely a pos/neg switch type thing, perhaps it's taking the place of a (-1)^n type coefficient?
Can you give an example of the exact input you're using that results in this in the output?
If the calculator is saying the result varies depending on the sign of one of the variables, or on the sign of a term defined on one of your variables, then I think you can eliminate the sign-specific stuff with a domain restriction. That's the | key, just to the left of the 7.
I've never ran into this kind of problem -- but calculus was 1994-1996 for me and I don't think I've exercised my calculator like you have yours. Can you post a specific expression that creates that sort of answer? I'd like to play with it and see if I'm right, or recommend something different if I'm not.
Edit: I say that because what you posted provides a "beast of an expression" but I don't see the sign() function in the result.
