### Displaying a series obtained by evaluating a Taylor series

Description of problem I would like to use Mathematica to display the series obtained by substituting a value for $x$ in a Taylor series expansion. The terms of the series will be rational numbers, ...

### How to put terms in lexicographic order?

Is it possible to have terms like f[w-c] be formatted like this and not like f[-c + w]. I use Mathematica (7.0) for simplifying ...

### Why does Mathematica order polynomial forms in reverse from traditional order?

I could very well be missing something obvious, but this has always bugged me with Mathematica and I don't know why it does it or how to fix it. If I enter any polynomial, say, x^2 + x - 1 for ...

### How do I get a two-term polynomial with a leading negative sign to display in the correct (i.e. textbook) order?

The first three expressions evaluate as expected and the polynomial is displayed in what I would call "textbook" form. The last expression, however, switches the order of terms. Mathematica employs ...

### Stopping Mathematica from reordering expressions [duplicate]

I want Mathemtica to stop manipulating my polynomials! I mean, I want the output of Print[3 x + 5 + x^2] to be just $3x+5+x^2$, not $5+3x+x^2$ as Mathematica ...

### HoldForm: how does it interact with nested evaluations?

Here's an example to illustrate the issue I'm having. right = 8 - y; left = y^2 + 6; integrand = HoldForm[Evaluate[right]] - HoldForm[Evaluate[left]] (I ...

### How to order terms in a polynomial in two variables negative lexicographically

I have several polynomials in variables p and q, each term in which has total degree n, a constant. I would like to output the polynomial in increasing powers of p (and hence decreasing powers of q), ...
How to simplify a polynomial in a order that I want? Assume that I have a polynomial here, for example, $a^3 b^4 c^2$, the order of symbels is the dictionary order, $a>b>c$. But what if I want ...
