The concept points is through the partitioning of job-seekers and seeking ways to define limits, and some of the points of the proof of the graphic linear inequalities often due to structural complexity, the amount of computation, it is difficult to find a breakthrough to let people do not know wher

The integral concept is asks through the division summation, but some which the limit the method defines because with the integral related inequality proof the structure are often complex, the computation load is big, difficult to find the breach, lets the human not know from where obtains

Integral sum is through the concept of segmentation defines the method to the limit, and some related to the integral inequality proof of often complex, compute-intensive, difficult to find a breakthrough, people do not know how to start
