Hi there,
maths can sometimes be weird and even more so the kinds of formulas
one needs to typeset occasionally ;-)
So here I need to typeset triangles and a variety of other polygons
right in the middle of a display formula. What I've been able to come
up with so far is something like this:
---
\starttext
\startuseMPgraphic{tetrahedral}
u := 10pt;
draw (0,0)--(2u,0)--(u,sqrt(3)*u)--cycle;
\stopuseMPgraphic
\startformula
\Phi(\useMPgraphic{tetrahedral})=F_{kln}^{ijm}\,v_iv_jv_kv_l\,
\delta_{j^*nk^*}\,\delta_{l^*n^*i^*}\,\Phi(\emptyset)
\stopformula
\stoptext
---
Now if I only knew how to properly align my MetaPost figure with the
rest of the formula … any ideas?
Cheerio,
Oliver
