Document Summary

Given a function f defined on an interval. [ a. b) , we want to calculate a number. the siynedarea under the graph of f between x=a and =b . * signed area means that area under the graph off and above the x-axis is counted positively, while the area below the x-axis and above the graph of f- is counted negatively. The symbol for this number is detiniteinteyral of f from =a to =b. , or (cid:8869) related notion : the indefinite integral f! 1-1 7 dx , and is called the the integral . just. In order to give a precise definition for this number , we need more notation +terminology . Sum notation: a compact way to indicate a sum. , especially when the terms follow a regular pattern which can be described by a changing variable lulled the indexvariable)
