Let S be the sum of the series.\r
\n" ); document.write( "\n" ); document.write( "Then, \"S+=+1+%2B+1%2F4+%2B+1%2F16+%2B+1%2F64+%2B+...\".
\n" ); document.write( "Multiply each term of the series by 4.
\n" ); document.write( "Then, \"4S+=+4%281%29%2B+4%281%2F4%29+%2B+4%281%2F16%29+%2B+4%281%2F64%29+...\".
\n" ); document.write( "Or, \"4S+=+4+%2B+1+%2B+1%2F4+%2B+1%2F16+%2B+...\".
\n" ); document.write( "Subtract S from 4S.
\n" ); document.write( "Then, \"3S+=+4\".
\n" ); document.write( "So, \"S+=+4%2F3+=+1%2B1%2F3\".
\n" ); document.write( "
\n" );
