comment Fitting Legendre polynomial - Integer constraints in Fitting functions
Are you sure you don't want to fit to a sum of such polynomials? That's what people usually do.

Reverted to original version of code because change wasn't necessary to answer the question.

The point is that the DisplayFormula Cell is already in TraditionalForm. You don't need to convert anything.

comment FrameTicks in BarChart
I can confirm this bug in version 8. So I'm tagging this as a bug that's specific to that version.

comment How can I stop Mathematica from re-arranging formulae in TraditionalForm?
Are you typing your formulas in an input cell? None of this would happen if you were using one of the cell styles that are meant for that purpose, like DisplayFormula. So you should perhaps clarify what you really want to do with the typed formulas eventually: i.e., use them only for display or do other calculations with them.

comment Fitting a rotated ellipse to data points
Could you provide some test data, add a definition of your desired "best fit" (weight functions), and list any Mathematica code you have tried? Otherwise this seems more like a math problem, not a Mathematica issue.

comment Drawing a Gradient Between Two Circular Arcs
Not sure if the gradient itself is supposed to radial or linear. In any case, this question seems to be related.
