How to Palatino, designed by Hermann Zapf, is an elegant font. To typeset a document in Palatino: <texcode>\usetypescript[palatino][ec]\setupbodyfont[palatino,11pt]</texcode> (I use 11pt because I find 12pt slightly too large, but choose your favorite size.) That setup uses Palatino as for text and mathematics. To set the mathematics in Euler (also designed by Hermann Zapf), <texcode>\usetypescript[palatino][ec]\definetypeface [palatino] [mm] [math] [euler] [euler] [rscale=1.03] \setupbodyfont[palatino,11pt]</texcode> (The rscale setting is to match the text Euler font with Euler for height to the Palatino height.) To get boldface mathematics symbols, <texcode>\usetypescript[palatino][ec]\definetypeface [palatino] [mm] [math] [euler] [euler][rscale=1.03]\definetypeface [boldmath] [mm] [boldmath][euler][euler][rscale=1.03]\setupbodyfont[palatino,11pt]</texcode> Here is an example: <context>\usetypescript[palatino][ec]\definetypeface [palatino] [mm] [math] [euler] [euler][rscale=1.03]\definetypeface [boldmath] [mm] [boldmath][euler][euler][rscale=1.03]\setupbodyfont[palatino,11pt] \def\thetavec{{\boldsymbol\theta}}\def\thetahat{\hat\thetavec} If $\thetavec$ is a vector, $\theta$ is its length, and $\thetahat$ isa unit vector in the $\thetavec$ direction,\startformula\thetavec = \theta\thetahat.\stopformula</context>
