\n" ); document.write( "We can use the two identities:
\n" ); document.write( " $\"%28sin%28beta%29%29%5E2+%2B+%28cos%28beta%29%29%5E2+=+1\"$
\n" ); document.write( " $\"2sin%28beta%29+cos%28beta%29+=+sin%282%2Abeta%29\"$
\n" ); document.write( "So the expression simplifies to:
\n" ); document.write( " $\"1+%2B+sin%282%2Abeta%29\"$ \n" ); document.write( "

\n" );
