looks true to me
\n" ); document.write( "Looking at the right side, \"85\" degrees is in the 1st quadrant
\n" ); document.write( "between \"0\" and \"90\" degrees, and sin is (+)
\n" ); document.write( "Therefore \"-sin%2885%29\" is (-)
\n" ); document.write( "--------------
\n" ); document.write( "Looking at the left side, \"-85\" degrees is in the 4th quadrant
\n" ); document.write( "where the sin is (-)
\n" ); document.write( "so, the equation says
\n" ); document.write( "\"-.9962+=+-.9962\"
\n" ); document.write( "
\n" );
