You can put this solution on YOUR website!
Sec A = 3 ==> cos A = 1/3 ==> \"1%2F9+%2B+%28sin+A%29%5E2+=+1\"\r
\n" ); document.write( "\n" ); document.write( "==>\"%28sin+A%29%5E2++=+8%2F9\"\r
\n" ); document.write( "\n" ); document.write( "==> \"sin+A+=+%282sqrt%282%29%29%2F3\" or \"-%282sqrt%282%29%29%2F3+\"
\n" ); document.write( "
\n" ); document.write( "
