comment Plot showing discontinuity where it shouldn't
@kguler Thank for for such an excellent explanation! I learnt about using limits in mathematica, especially inside a plot, as an additional bonus. :) It's interesting that you spotted that taking limits makes mathematica realize that the curve is continuous. cool beans!

comment Plot showing discontinuity where it shouldn't
@Artes but 1/2 (2 a x + (a - x)^2 UnitStep[-a + x]) is a continuous and even differentiable function whose derivative should be Max[x,a]. I guess MMA is not able to figure this out and I need to communicate it to MMA somehow.

@Artes ok that worked. Thanks! Do you have a sense of why I am getting an Intermediate when I differentiate?

@belisarius thanks. I'm happy to hear that I am complicating things. I'll try to find you in chat sometime.

@Mr.Wizard no but I suppose I could always sort it on the first column.

comment Export to Excel gives error for large lists
Thanks a lot for your answer. Do you have a sense of why this is working for *.xls but not for *.xlsx ?

comment Exporting data to a new excel sheet of a pre-existing excel file
@SjoerdC.deVries I spent a bit of time trying to mimic the .NET but I couldn't get it to work. Thanks for linking to it. I'm not very far from getting it. Whatever I am doing, does open the right excel file but as of now closes it right back. I'll look at it again in a few months when I have more time. Right now I have just switched to saving data as "*.dat" Thanks :)

comment saving Manipulate data inside a notebook
@MarkMcClure Thanks a lot for your answer. I used the SaveDefinitions right now and picked it as the accepted answer because that seemed simpler but I will now try your cell initialization method. I'm sorry, I can't believe that it has taken me 8 days to respond. Thanks a lot.

comment saving Manipulate data inside a notebook
@Sjoerd C. de Vries and Mark McClure. Thanks for both your answers. Since I had to accept one, I went with Sjoreds. Right now I am using SaveDefinitions but when I have to make an important presentation, I will not take a chance and use Initialization.
