Hello. In Mathematica 5, I seem to get a good approximation, along with the standard warning message: Needs["Algebra`InequalitySolve`"] InequalitySolve[Sin[x] > 0.5, x] InequalitySolve::npi:A nonpoly... Report Spam

The paraxial wave equation for an optical beam propagating in the z direction is in essence D[ f[x, z], z] = I alpha D[ f[x,z], {x,2}] I'd like to integrate this forward in z starting with some spec... Report Spam

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... Report Spam

First, you have to load a package : <Algebra`InequalitySolve` Then, it would be good to reed what this function does : InequalitySolve[expr,x] : "find all real values of x that satisfy the expressio... Report Spam
