WolframAlpha[] give results but not parse!

In Mathematica 8.0, the following gives the expected explicit solution, graphs, etc.: WolframAlpha["solve dy/dt=2y(1-y)"] It even tells me the interpretation as "solve y'(t)=2y(1-y)". Of course, just using input =solve dy/dt=2y(1-y) gives the same results. However, the following (as well as the Ctrl= input form for it) gives no Mathematica translation of the input: WolframAlpha["solve dy/dt=2y(y-1)","MathematicaParse"] It is surprising that WolframAlpha "understands" what I asked but cannot actually tell me in Mathematica syntax the same thing! Or am I missing something? -- Murray Eisenberg Internet: murray at math.umass.edu Mathematics & Statistics Dept.
