# How to format latex-quality math code in Mathematica?

I'm giving a presentation with a notebook as a slide show and would like some of my equations to appear professional. For example I have an integral function with a square root in the denominator but the integral symbol and fraction with the square root appears odd, not sized correctly, an unprofessional-looking when I try to display it with Text and Style. Here is an example of my code. Could someone suggest a way to make this expression appear latex-quality in a notebook? I only want to display it and several others as a label underneath plots.

Text[Style["\[Zeta]=\[Xi]+\[Eta]I=\!$$\*SubsuperscriptBox[\n StyleBox[\"\ [Integral]\",\nFontSize->36], \"0\", \"z\"]$$\!$$\*FractionBox[\(A$$,
SqrtBox[$$\((1 - \*SuperscriptBox[\(w$$, $$2$$])\) $$(\*SuperscriptBox[\(a$$,
\$$2$$] - \*SuperscriptBox[$$w$$, $$2$$])\)\)]]\)\[DifferentialD]w", 16]]

• Have you seen TraditionalForm. – Edmund Jul 26 '17 at 10:57
• Have you seen MaTeX? – C. E. Jul 26 '17 at 11:10
• I'm familiar with MaTeX but not sure I could use it as this is going to be a presentation at the Mathematica conference in October and I have to have everything on a thumbdrive so don't want to carry any extra software that I may have problems with. This from a previous reply is close to perfect: – Dominic Jul 26 '17 at 11:44
• Row[{Spacer[100],Style[HoldForm[f[w]=A/Sqrt[(1-w^2)(a^2-w^2)]],20,Bold]//TraditionalForm,Spacer[150],Style[ HoldForm[[Zeta] = [Xi]+[Eta] I = Integrate[A/(Sqrt[(1 - w^2)(a^2 - w^2)]), {w,0,z}]], 20,Bold]//TraditionalForm,Spacer[150], Column[{Style[HoldForm[[Eta]=\!( *SubsuperscriptBox[([Integral]), (0), ([Alpha])]( *FractionBox[(1), (R + [Rho]\ cos ((t)))] [DifferentialD]t))],30,Bold]//TraditionalForm,Style[HoldForm[[Xi]=[Phi]],30,Bold]//TraditionalForm}]}] – Dominic Jul 26 '17 at 11:44
• I think Matex should be integrated into Mathematica, so you do not have to worry about carrying additional software such as texlive, etc... to make it work. Matlab allows one to display labels and titles using Latex. It is build-into Matlab. But why can't you create the plots at home and save them as images? Then during presentations, you just show them? Why run the code to generate the plots again? Or are you making changes at presentation time so plots will be different? – Nasser Jul 26 '17 at 11:53

In my opinion this will give somewhat better looking typesetting than the code you posted in a comment to your question.

Style[Row[
{Spacer[60],
HoldForm[f[w] = A/Sqrt[(1 - w^2) (a^2 - w^2)]],
Spacer[150],
HoldForm[ζ = ξ + η I = Integrate[A/(Sqrt[(1 - w^2) (a^2 - w^2)]), {w, "\[ThinSpace]0", "\[ThinSpace]z"}]],
Spacer[100],
Column[
{HoldForm[η = Integrate[1/(R + ρ Cos[t]), t]],
HoldForm[ξ = ϕ]}],
Spacer[20]}}],
