知识打卡(2)Mathematica求不定积分和绘制图形
分享兴趣,传播快乐,增长见闻,留下美好。亲爱的您,这里是LearingYard学苑!今天小编为大家带来Mathematicad求不定积分以及函数作图。不定积分/Indefinite integral
不定积分是微积分中一个重要概念,在规定区间范围内,如果有f=F",则F就是f的不定积分。从这个定义中,我们可以知道求不定积分就是求哪一个函数求导之后是f。
我们平时可以人工计算出不定积分,但为了提高计算效率,今天就跟随小编一起学习如何使用Mathematica求不定积分吧!
Indefinite integral is an important concept in calculus. Within the specified interval, if f = f ", then f is the indefinite integral of F. From this definition, we can know that solving indefinite integral is to find which function is followed by F.
We can calculate the indefinite integral manually at ordinary times, but in order to improve the calculation efficiency, let"s learn how to use Mathematica to solve the indefinite integral with Xiaobian today!
求不定积分要掌握Integrate[],下面将以具体的例子进行说明。
使用Integrate[]求解下图所示f的不定积分。
To solve the indefinite integral, we should master the integration [], which will be explained with specific examples below.
Use integrate [] to solve the indefinite integral shown f in the figure below.
求解有上限和下限的不定积分如下图所示:
Solve the indefinite integral with upper and lower limits as shown in the figure below:
绘制图像/Draw image
绘制图像需要使用的函数为plot[],这个是绘制二维图像,使用方法如下图所示:
The function to be used to draw an image is plot [], which is to draw a two-dimensional image, as shown in the following figure:
绘制3D图型,则使用plot3D[],使用方法如图所示:
To draw a 3D pattern, use plot3d [], as shown in the figure:
