Oliver,

Did you load the package containing InequalitySolve?

First,

    Needs["Algebra`InequalitySolve`"];

Then you can try

     InequalitySolve[Sin[x] > 0.5, x]

However, I'm not sure what you expect for an answer!

Hi,

I've Mathematica 4.1 on Linux. If I try to solve this:

InequalitySolve[Sin[x] > 0.5, x]

Mathematica recalls it without solving it. Why? What do I've to do?

thx,
Oliver
