When I run
\!\(Solve[{P\_InnocentI[4\/5, sI, sG, 1, 1] == 1\/2, P\_InnocentG[4\/5,
sI,
sG, 1, 1] == 1\/2}, {sI, sG}]\)
(where p_foo are functions defined previously) I get no solution. But
when I run
\!\(Solve[{P\_InnocentI[.8, sI, sG, 1, 1] == 1\/2, P\_InnocentG[.8, sI,
sG, 1, 1] == 1\/2}, {sI, sG}]\)
I get a solution. That is, switching .8 for 4/5 gives me a solution.
What's going on here? Does Solve care whether I use decimals or
fractions? I have a more complicated Solve of the same functions, and
now I don't know if there's really no solution, or if Solve is just
misbehaving.
