Describe the relationship between the definite integral and net area When we defined the definite integral, we lifted the requirement that f(x)f(x) be nonnegative. But how do we interpret “the area under the curve” when f(x)f(x) is negative?

6 The Definite Integral and Area Last class, we saw that we could estimate the total change in a quantity from its rate of change using a left or right hand sum. This fact will motivate us in defining the so-called definite integral , which will be our primary topic of study in this...
Definite Integral and Area: One of the applications of the definite integral is the calculation of the area between given curves. To solve an area, we must apply the definite integral theorems: 1) {eq}\displaystyle \int_{a}^{b} \left( f(x) \pm g(x) \right) \ dx = ...
Integration has a wide variety of applications.Today you'll learn to use a definite integral to find the area of a region bounded by two curves.Area is nonnegative number.When we find the area of a region above theχ-axis,the area is positive.When we find the area of a region below ...
英语翻译net signed area 是什么就好.上下文是:the definite integral is defined informally to be the net signed area of the region in the xy-plane bounded by the graph of ,the x-axis,and the vertical lines x = a and x = b. 答案 应该指的是带正负号的净面积.譬如,x=a和x=b之间的graph...

Definite Integrals: The integration can be regarded as the summation of some data. The definite integral {eq}\int_a^b {f\left( x \right)dx} {/eq} represents the area between the curve of the function {eq}y = f\left( x \right) {/eq} and the x-axis between the lines {eq}...
