We know that there are many HTML editing controls on Web development, such as FCKeditor, CKEditor, Kindeditor, and so on, and many are doing well, and although WinForm has WebBrowser controls, the default control is not allowed to edit content. You can display Web pages only. WinForm development inside, some use the RichTextBox control to edit HTML, there are some WebBrowser controls to achieve the content of editing, which I think the best thing to do is the

}{((2^{n+1}-1) π) ^2})} So, when n is large, \frac{1}{2^{n+1}} can be ignored and we have $${\,8\, (\frac{1}{π^2} + \frac{1}{(3π) ^2}+\frac{1}{(5π) ^2}+\frac{1}{(7π) ^2} +\dots + )}= 1$$ i.e. $$\frac{1}{1^2}+\frac{1}{3^2} +\frac{1}{5^2} +\frac{1}{7^2} +\cdots =\frac{π^2}{8} $$ Now we're only one step away from the conclusion. Make $\zeta (2) = 1/1^2 + 1/2^2 + 1/3^2 + 1/4^2 + 1/5^2 + \dots$ So $\zeta (2)/4 =

The byte order usually has tw

1, bit (bit)From the English bit, transliteration is "bit", indicating bits. Bits are the smallest unit of data storage within the computer, and 11010100 is a 8-bit binary number. A bits can only represent 0 and 12 states; Two bits can represent 00, 01, 10, 114 states; The three-bit binary can represent eight states.2, Bytes (byte)From English byte, it is customary to use uppercase B to denote.

Basic byte order For a single byte (A byte), Most processors process bits in the same order, so the storage method of a single byte is generally the same as the transmission method. For multi-byte data, such as integers (4 bytes in 32-bit machines), there are two main stor
