to_poly_solve returns some solutions:
%i4: load(to_poly_solver)$
%i5: to_poly_solve(A*sin(x)+B*cos(x)=C,x);
%o5: %union(%if((B-%i*A=0) %or
(sqrt(C^2-B^2-A^2)-C#0),[x=2*%pi*%z15-%i*log(C/(B-%i*A)-sqrt(C^2-B^2-A^2)/(B-%i*A))],%union()),%if((B-%i*A=0)
%or (sqrt(C^2-B^2-A^2)+C#0),[x=2*%pi*%z17-%i*log(sqrt(C^2-B^2-A^2)/(B-%i*A)+C/(B-%i*A))],%union()))
