Solve the following equation exactly for 0≤θ≤2Π with θ in radians.
\n" ); document.write( "2sin2(θ) - sin(θ) - 1 = 0
\n" ); document.write( "sin(θ)(2sin(θ)-1)=0
\n" ); document.write( "..
\n" ); document.write( "sin(θ)=0
\n" ); document.write( "θ=0, π

\n" ); document.write( "2sin(θ)-1=0
\n" ); document.write( "sin(θ)=1/2
\n" ); document.write( "θ=π/6, 5π/6 \n" ); document.write( "
\n" );
