(1-COSX)/(x^2) How to find the integral from negative infinity to positive infinity? the problem needs to be simply deformed before usingParseval's theorem, and then calculate the result. 1. Simple deformation: primitive = make, there are ... =; 2. Parseval's Equation and therefore the original type =. 3.

1. Infinite
In Java, infinity is defined as a floating point number, which is divided into POSITIVE_INFINITY and NEGATIVE_INFINITY.
2. null
Null can be considered as a special reference type in java. It can be assigned to any referenced type variable
infinity and Nan
(1) What do they mean?
Javascript predefines the global variables infinity and Nan to represent positive infinity and non-numeric values.
(2) Where can I see these two horses?
Arithmetic Operations in Javascript do not report errors when overflow, underflow, or division by zero.

as hardware raid, and features are not as good as hardware raid.
Next we will introduce various RAID technologies
I. RAID 0
The band technology is used to write data in parallel on multiple disks in bytes or bits (the starting offset of each disk is the same, and the subsequent segments of a certain number of bytes, i/O read/write performance can be improved, but it does not have data redundancy like raid1. Once the hard disk fails, it will be done.
