Use the sum or difference identities to find the exact value of the trigonometric function.
\n" ); document.write( "sin(735 degrees)
\n" ); document.write( "
One of the terminal angles of \"735%5Eo\" is 735 - 2(360), or 735 - 720 = \"15%5Eo\"
\n" );
document.write( "Difference of two angles' identity associated with \"15%5Eo\" is: 
\n" );
document.write( "\"sin+%2845%5Eo%29+=+sqrt%282%29%2F2\"
\n" );
document.write( "\"cos+%2830%5Eo%29+=+sqrt%283%29%2F2\"
\n" );
document.write( "\"cos+%2845%5Eo%29+=+sqrt%282%29%2F2\"
\n" );
document.write( "\"sin+%2830%5Eo%29+=+1%2F2\" \n" );
document.write( "
\n" );
