solving equations (are there man pages?)



I am new to (x)maxima.  The following does not seem to execute (C4); 
it just sits there.  What am I doing wrong?  OR Are there man pages 
(ala Linux)?  Thanks :-)

d=%pi/6;
g1=%pi/3;
g2=%pi/4;
solve([(u+cos(d)*sec(g1))^2+(v-sin(d)*sec(g1))^2=(tan(g1))^2,
(u+sin(d)*sec(g2))^2+(v-cos(d)*sec(g2))^2=(tan(g2))^2],[u,v]);
