I'm embarrassed to need help with this, given how trivial it should be, but ... Does anyone know of a package suitable for solving triginometry problems such as (Upper case are angles, lower case is opposite side) A=12 Degree a=5 b=17 C<90 Degree I've written something (which works) using repeated applications of Solve with the Sin and Cos rules which does the job very badly(!). However, it doesn't cope with the _generic_ case of _any_ mixture of (minimally sufficient) information, and I've had to go about the solution in several steps to get it to work properly.
