Note that the variable YX does not appear in the integrand! By the way, if you answer Pos, you get the error SIGN called on an imaginary argument: %I and if you answer Neg, you get the error Quotient by a polynomial of higher degree (with default GCD) Maxima 5.9.0 gcl 2.5.0 W2k  You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=104933&aid=924868&group_id=4933

It's trying to solve yx  sqrt(q^1+1)  1 for q. Perhaps for some kind of substitution.
