Use the identity:
\n" ); document.write( " $\"+%28+sin%28+2%2Atheta+%29+%29%5E2+%2B+%28+cos%28+2%2Atheta+%29+%29%5E2+=+1+\"$
\n" ); document.write( "------------------
\n" ); document.write( "

\n" ); document.write( " $\"+1+-+%28+sin%28+2%2Atheta+%29+%29%5E2+=+%28+cos%28+2%2Atheta+%29+%29%5E2+\"$ \r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
