1. If A+B=90 degree and Sin A=1/3.Then Sin B is?
\n" ); document.write( "sin(B) = cos(A)
\n" ); document.write( " $\"cos%28A%29+=+sqrt%281+-+sin%5E2%28A%29%29\"$
\n" ); document.write( "= $\"sqrt%288%2F9%29\"$
\n" ); document.write( "= $\"2sqrt%282%29%2F3\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
