There is a pottery pot, the pottery can be y=2+cosx by the function, intercept x=z1 to the X=Z2 section, the formation of the rotating body, pottery pot only the bottom x=z1, no lid.Ask how much water the pot can multiply (volume), and its surface area.Volume is still relatively good, directly with the volume formula of the rotary Body, PI*∫[Z1,Z2] (2+COSX) 2dx= pi* (4SINX+SIN2X/4+9X/2 | [Z1,

POST method. Therefore, if we want to upload a file by using a Trojan horse, we only need to send a POST request with the file write command to the url containing a sentence in the remote service. for example: POST: 1 = @ eval ($ _ POST [z0]); z0 = echo $ _ SERVER ['document _ root']; The code above contains two parts: 1. one-sentence password 2. send the php code to the server for execution Now that we know the principle, we only need to send the following POST request to complete the functio

union all. The difference is that UNION deletes duplicate rows from the result set. If union all is used, ALL rows are included and duplicate rows are not deleted.Difference between UNION and union all:Union check already existsUnion all does not checkFor example, the output of select 'A' union select 'a' is a row.For example, select 'A' union all select 'A', and the output is two rows.2. The following example clearly shows and understands the differences between

A Day has A Q times. Each time John would find a new star in the sky, or he wants to know how many stars between (X1,Y1,Z1) and (X2,Y2,Z2).Input The first line contains a single integer T (1≤t≤10) (the data for q>100 less than 6 cases), indicating the number of test

as the expression returns a positive value smaller than MAXVALUE (the largest possible positive integer.Because MySQL does not have the global index concept and only has a local partition index, for this reason, if a table has two or more unique indexes, this table cannot be partitioned. The columns in the database of the partition function application must be the primary key of MySQL; otherwise, the database cannot be partitioned. [Z2]For tables tha

if the administrator finds a Trojan, it cannot intercept any code you have executed. There is almost no hope for the server to break through and only capture packets locally. The following code uses the packet capture tool to capture the POST data of the new file.

decomposition method. The first four algorithms are most commonly used, the basis of which is the back-blanking principle. The so-called back-blanking principle, that is, relative to the point of view of the object facing the surface is not visible, should be hidden. ----1. Plane Formula method----according to the analytic Geometry principle, the standard plane equation can be used to determine whether the given point is on the front or back of the plane. The plane formula method uses this prin
