Two different plots for square root and polyroot function

[vveeran]

Dear all,

In my previous thread, I asked the question,

'What is the reason for 2 different plots when plotted using Square root and polyroot function ?.

Mr. Stuart and others told  that it is due to mixing up of signs, so, to avoid the problem

he suggest me to change the Laguerre to companion matrix by right clicking polyroots and the problem was solved.

But, In this attached example worksheet, I also changed Laguerre to companion matrix by right clicking polyroots,

even then also I am two different plots for polyroots and square root function.

Could anyone help me.

Thanks.

See attached (though you probably won't like the programming part again!).

However, you really need to look at the difference between range variables and standard variables.  Stuart has written some good stuff on this (though I can't find it off-hand).
