Hi
I have a question regarding Matlab Symbolic and trig equations.
I have a trig equation with various symbolic variables. I would like to solve the equation by including bounds on the angle.
For example, when I currently try to solve for the angle 'x', I obtain two solutions. Sometimes when I have quadratic equations, I end up with 4 solutions.
Is there an elegant way to include the bounds? Eg. if 'x' lies from pi/2 to 2*pi, I only want the solutions to be in those quadrants.
Thanks in advance
Amir

I'm not sure you can constrain the solution to specific quadrants, but you can constrain the solution to an extent. See Name-Value Pair Arguments, particularly 'MaxDegree' and 'PrincipalValue' in solve.
