$\"sec%28A%29=sqrt%285%29\"$
\n" ); document.write( "So,
\n" ); document.write( " $\"1%2Fcos%28A%29=sqrt%285%29\"$
\n" ); document.write( " $\"cos%28A%29=1%2Fsqrt%285%29\"$
\n" ); document.write( " $\"cos%28A%29%5E2=1%2F5\"$
\n" ); document.write( "But you know that,
\n" ); document.write( " $\"cos%5E2%28A%29%2Bsin%5E2%28A%29=1\"$
\n" ); document.write( " $\"1%2F5%2Bsin%5E2%28A%29=1\"$
\n" ); document.write( " $\"sin%5E2%28A%29=4%2F5\"$
\n" ); document.write( " $\"sin%28A%29=0+%2B-+2%2Fsqrt%285%29\"$
\n" ); document.write( "So then,
\n" ); document.write( " $\"csc%28A%29=0+%2B-+sqrt%285%29%2F2\"$ \r
