Re: Math typesetting problems

[Otared Kavian <otared@gmail.com>]

Hi Janne,

Personnally I prefer to use the Plain TeX alternative \over (which works fine in ConTeXt), that is
	${a \over b}$
instead of 
	$\frac{a}{b}$
Compare the following two outputs in the example you want to typeset: I think the second is more or less what you want

\starttext
Using \type{\frac} gives:
\startformula
f_{B_t | B_s = S, B_u = U}(x) = \frac{e^{-\frac{(u-s)x^2 - 2x(S(u-t) +
U(t-s)) + \frac{(S(u-t) +
U(t-s))^2}{(u-s)}}{2(t-s)(u-t)}}}{\sqrt{2\pi\frac{(t-s)(u-t)}{u-s}}}
\stopformula
\blank
Using \type{\over} gives:
\startformula
f_{B_t | B_s = S, B_u = U}(x) = {
e^{-{(u-s)x^2 - 2x(S(u-t) + U(t-s)) + 
{(S(u-t) + U(t-s))^2 \over (u-s)} \over 2(t-s)(u-t)}} \over 
\sqrt{2\pi {(t-s)(u-t) \over u-s}}}
\stopformula

\stoptext

Best regards: OK
