 Author Comment/Response jf 04/03/13 7:29pm The domain argument can be one of Reals, Integers, and Complexes. To put constraints on the solution, AND the equation with the constraint(s). In[2]:= Solve[2*Sin[x] + 1 == 0 && 0 < x < 2*Pi, x] Out[2]= {{x -> (7*Pi)/6}, {x -> (11*Pi)/6}} In[3]:= N[%] Out[3]= {{x -> 3.66519}, {x -> 5.75959}} The reference page for Solve has an example of this, under Basic Examples, Examples, scroll down to "Solve an equation over the positive integers" http://reference.wolfram.com/mathematica/ref/Solve.html#128483034 Solve deals primarily with linear and polynomial equations. For equations with trig functions, you may need to use FindRoot. URL: http://reference.wolfram.com/mathematica/ref/Solve.html#128483034,
