Mar 6 comment Logical Circuit @Maddi Restart your mathematica session and try again. Mar 6 comment Two identical functions give different answers @george2079 It's more interesting if you also consider that FullForm@Cos[u - t] == FullForm@Cos[t - u] Mar 6 comment Logical Circuit It seems pretty easy. Have you seen the docs for the logical operators and BooleanTable?

The problem was caused by the lexicographical ordering of the symbol names, as strange as it may seem. Do you remember that question?

Mar 6 comment Not seeing plot of solution returned by NDSolve @BohanLu To put it in simple words: you show us a piece of code displaying some mastery of Mathematica. We (the readers) in absence of a sentence stating that you aren't the author, answer in a straightforward way because you should be able to understand that. Then you ask a really first-day-with-Mathematica question. Something doesn't compute here. Mar 6 comment Not seeing plot of solution returned by NDSolve Also, I don't believe you need DynamicModule[] for that Mar 6 revised Not seeing plot of solution returned by NDSolve added 7 characters in body Mar 6 comment How can I convert a Piecewise into a nested If? Just joking. Or not :) Mar 6 comment How can I convert a Piecewise into a nested If? @rasher He's migrating the code, so no lists on the new platform either :)} Mar 6 answered Not seeing plot of solution returned by NDSolve Mar 6 comment Not seeing plot of solution returned by NDSolve have you been able to run the NDSolve[]and/or the ParametricPlot[] outside the Manipulate (I mean as a stand-alone code)?
