Approximation integration by using rectangles |
|
| Abstract: | <正>In calculus,two famous problems are well known.The one problem of finding the tangent line led us to the derivative.The other problem of finding area led us to find the definite integral.In this paper,we will learn how to approximation integration by using rectangles.1.What does the Riemann sum mean?A given function y=f(x)is continuous on the intervala,b].We divide the interval |
