**Many** days passed since I updated last time.Since I was busy with my Software Engineering project rencently,yet I have no time taking care of  my blog.Today is a little note of some critical points in my Numerical Method class,and I paln to write another one after the presentation of my SE project,which is due on the day after tomorrow.  
Below is my notes of Numerical Integration:  
We know that some integrations are difficult to compute by hands,for example,indeterminate or improper forms.And numerical integration is a primary tool used by engineers and scientists to obtain approximate answers for those integrals.  
Some of the closed Newton-Cotes quadrature formulas:  <commit_msg>20160516b<commit_after>---
