Hey,
If anyone here likes working on these problems, I'm working on a couple more. I finished the first two. These go:
1. Vx Vy (Fxy ---> ~Fyx) |- -ExFxx
(now my work - maybe wrong
2. Vy (Fay ---> ~Fya) 1,VE
3. (Faa ---> ~Faa) 2,VE
4. | Faa H(for -->E)
5. | ~Faa 3,4, CON
6. Faa
7. ~~Faa 3,6, MT
(I find this hard to articulate in the logical format, but basically, if ~Faa is proved wrong by Faa in line six(~(~Faa)), then MT says that ~Faa can be infered...)
8. ~Faa
9. -ExFxx 8, EI(can I do this?)
Actually ended up working it out as I posted it. Is it right, though? Btw, does anyone know the tex way to do this?
Test: [tex]VxEy(Mxy -> Fxy) [/tex]
Didn't work.
