Dear Murray,

Thank you for your help. Here is an equation I typed into Mathematica:

In[1]:= (2 m^2 =CF=83^2 Exp[-((
2 m^2 =CF=83^2 (((x - Subscript[x, i]) -
Subscript[v, i] (t - Subscript[t, i]))^2 + (y - Subscript[y,
i])^2))/(
4 m^2 =CF=83^4 + =E2=88=87^2 (t - Subscript[t, i])^2))])/(=CF=80 (4 m^2 =CF=83^4 +
=E2=88=87^2 (t - Subscript[t, i])^2))

And here is the output form of the same equation;

Out[1]== (2 E^(-((2 m^2 \[Sigma]^2 ((x - (t - Subscript[t, i]) Subscript[v,
i] - Subscript[x, i])^2 + (y - Subscript[y, i])^2))/(
4 m^2 \[Sigma]^4 + \[HBar]^2 (t - Subscript[t,
i])^2))) m^2 \[Sigma]^2)/(\[Pi] (4 m^2 \[Sigma]^4 + \[HBar]^2 \
(t - Subscript[t, i])^2))

And here is the "copy as LaTeX" form of the preceding equation:

\frac{2 e^{-\frac{2 m^2 \sigma ^2 \left(\left(x-\left(t-t_i\right)
v_i-x_i\right){}^2+\left(y-y_i\right){}^2\right)}{4 m^2 \sigma ^4+\hbar ^2
\left(t-t_i\right){}^2}} m^2 \sigma ^2}{\pi  \left(4 m^2 \sigma ^4+\hbar ^2
\left(t-t_i\right){}^2\right)}

The constants in the numerator are not grouped together, the (x-x_i) term
has been rearranged, and the velocity term does not preceed the time term. I
would like to get the exact same equation into LaTeX as I entered into
Mathematica.

Suggestions?
