Hi all, I have a problem.. Solve this equation: sinx+cos(2*x)==1. when I use Matlab:

solve(sin(x) + cos(2*x) == 1, x)
ans =
      0
   pi/6
(5*pi)/6

But I want to display all values of "x" when x=[-2*pi:2*pi]. Plz help me......thanks,

The solve() accessible directly from MATLAB cannot do that. Use the MuPAD solve()

feval(symengine, 'solve', sin(x) + cos(2*x) == 1, sym('x = -2*pi .. 2*pi'))
