Let's call theta, q, for simplicity.
\n" ); document.write( "sin^2(q) + cos^4(q) =
\n" ); document.write( "sin^2(q) + [cos^2(q)]^2 =
\n" ); document.write( "sin^2(q) + (1 - sin^2(q))^2 =
\n" ); document.write( "sin^2(q) + 1 - 2sin^2(q) + sin^4(q) =
\n" ); document.write( "sin^4(q) - sin^2(q) + 1 \n" ); document.write( "

\n" );
