You can put this solution on YOUR website!
This can be factored in terms of sin(x) as:
\n" ); document.write( "(2sin(x)-1)(sin(x)-2) = 0
\n" ); document.write( "Thus either sin(x) = 1/2 or sin(x) = 2
\n" ); document.write( "Clearly the 2nd solution is impossible, so the solution is all values of x for which sin(x) = 1/2
\n" ); document.write( "i.e. x = pi/6, (5/6)pi, ...
\n" ); document.write( " \n" ); document.write( "

\n" );
