   If I take what the OP passed to Wolfram Alpha and add in the missing   
   operators I get this:   
      
   (1/sqrt(2))*sin((1/8-((6*(atan(1/4*(-20-12*sqrt(3))-sqrt(7*(7+4*   
   qrt(3)))+sqrt(102+58*sqrt(3)+142*sqrt(7/(7+4*sqrt(3)))+82*sqrt(2   
   /(7+4*sqrt(3)))))))/pi))*2*pi)   
      
   Passing that to a calculator program I get:   
      
   ~0.33071891388307382398   
      
   which is pretty close to SQRT(7)/8.
