document.write( "\"sin%5E%28-1%29%281%2F7%29\"  is  \"arcsin%281%2F7%29\".\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So,  they want you calculate  \"tan%28alpha%29\",  where \"alpha%29\" = \"arcsin%281%2F7%29\".\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Since  \"alpha%29\" = \"arcsin%281%2F7%29\",  it means that  \"sin%28alpha%29\" = \"1%2F7\".\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then  \"cos%28alpha%29\" = \"sqrt%281-sin%5E2%28alpha%29%29\" = \"sqrt%281-%281%2F7%29%5E2%29\" = \"sqrt%281-1%2F49%29\" = \"sqrt%28%2849-1%29%2F49%29\" = \"sqrt%2848%29%2F7\" = \"%284%2Asqrt%283%29%29%2F7\".\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Finally,   \"tan%28alpha%29\" = \"sin%28alpha%29%2Fcos%28alpha%29\" = \"%28%281%2F7%29%29%2F%28%284%2Asqrt%283%29%29%2F7%29\" = \"1%2F%284%2Asqrt%283%29%29\" = \"sqrt%283%29%2F12\".\r\n" );
