 Feb22 comment Behaviour of Simplify when used with ArcTan and ComplexExpand along with assumptions Thanks you were right. On removing the assumption L>0 from the Simplify[] and the results match! Feb20 asked Behaviour of Simplify when used with ArcTan and ComplexExpand along with assumptions Feb16 accepted Plotting ContourLabels on ContourPlot3D Feb5 comment Plotting ContourLabels on ContourPlot3D Thank you for the solution Feb4 revised Plotting ContourLabels on ContourPlot3D clarification Feb4 comment Plotting ContourLabels on ContourPlot3D I would like to add the contours for the mesh (black) lines here Feb4 comment Plotting ContourLabels on ContourPlot3D @Artes : Thanks for pointing it out - the solution was to overlay the different plots. Whereas in this case of plotting contourLabels, one cannot user overlay (at least directly), since the position of the contourlines are not known apriori. Maybe one can get the contours from the expression (mathematica.stackexchange.com/questions/20281/…) and then evaluate the value of the function there and put a value there. But I was interested in knowing if there is a way to get it done using contourLabels Feb4 asked Plotting ContourLabels on ContourPlot3D Dec5 awarded Nice Question Oct30 comment Bound on number of function evalulations in FindMinimum to make sure it performs utmost iters no of evals, need to replace >= with = (can't edit it - min num of chars required for edits to be accepted) Oct30 accepted Bound on number of function evalulations in FindMinimum Oct30 comment Bound on number of function evalulations in FindMinimum +1 for fval = fun[x]. It works Oct29 asked Bound on number of function evalulations in FindMinimum Oct29 comment Shaving the last 50 ms off NMinimize @OleksandrR. Is there an equivalent for FindMinimum. I tried Trace[FindMinimum[x Cos[x], {x, 2}], TraceInternal -> True] and I see something like OptimizationInternalModifiedCholesky\$4575`.
