improved formatting and removed mysticism. This looks like a good answer/example otherwise

| Jan 13, 2014 at 19:13 | comment | added | Douglas Zare | It is wrong to suggest that this is similar to trisecting an angle, solving the general quintic in radicals, solving the halting problem, or proving AC/CH. How can you say something is unprovable or will never be proved while looking at 3 proofs which simply don't seem fully satisfactory from one perspective? So, $-1$ for that flagrantly incorrect and misleading statement. | |
| Jan 13, 2014 at 13:43 | comment | added | Wolfgang | @DouglasZare: Of course. I suppose Houdini meant "it's not provable without evaluating the very integral", in other terms: it cannot be transformed into a "non trivial" (in whatever sense??) integral over a symmetric function in $\alpha$ and $\beta$. BTW I would doubt such an absolute statement. It might be worth trying to write $f( \alpha,\beta)\sin(\pi \alpha)\sin(\pi\beta)$ as a triple integral, using suitable different integrals with values $\sin(\pi \alpha)$ and $\sin(\pi\beta)$. | |
