 Apr 20 comment How do I construct and list an operation on numbers as a function? your try 3 needs an i in the iterator {i,1,100}.

We could probably think of ways to speed it up a bit, but in the end you are finding a lot of roots of cubic polynomials. Apr 15 answered Why do I encounter 1/0 expression Apr 15 comment Why do I encounter 1/0 expression do you realize your function (moment) is discontinuous? Apr 15 comment How to reverse values of x along x-axis ParametricPlot[{x - 10, F[x]}, {x, 0, 10}, AspectRatio -> 1] ? Apr 15 comment How to calculate accurate answer in Mathematica? I guess you need to add a level, root the tree at numeric, with branches to number , symbolic (eg pi) , and expressions (eg Sqrt[2] ) Apr 14 comment Different interpretation of system of equations the convention is to order the roots real first in increasing order. Remember c is negative so 11c < .7 c Apr 5 comment Simplifying expressions containing unit of zero magnitude try Simplify[....,Assumptions->Element[k,Reals]] Apr 4 awarded Nice Answer Apr 4 comment ListPlot and Show n plots from two lists with large n have a look at Multicolumn (I assume you want 100 separate plots not one plot with 100 lines ) Apr 2 revised NSolve takes too long time! added 60 characters in body Apr 1 comment Multi-index variable depending on signature of permutation of indices evaluate this: NestList[RotateLeft,{1, 2, 3}, 2], it should be clear.
