应网友之约,讲解一些典型的有理函数的不定积分计划分4个视频,讲解 ∫1/(x^3+1) dx,∫1/(x^4+1) dx,∫1/(x^5+1) dx,∫1/(x^6+1) dx 这4个有理函数的不定积分。有理函数不定积分的一般计算方法,在这写不下,有兴趣的朋友可去我的动态查看。视频中用到的sin18°,cos36°
第一个注意到分母可以变成【3+cos(2x)】/2而正好sin(2x)dx=-dcos(2x)/2题目就转化为-∫dcos(2x)/【3+cos(2x)】 2022-01-23 12:134回复 晓之车高山老师 其实up表达的意思就是,被积函数某个地方稍有改动,对应不定积分表达式就可能有很大的变化,甚至完全不同 2022-01-24 03:072回复 QNのstarlake up主...
现在我们来观察一下 y=\sin(2x) 的图像,可以发现当0<x<π/4时sin(2x)>0,所以 \sin(2\xi)>0 。因此当R趋近于+∞时,整个积分就变成零了。 \lim_{R\to\infty}\left|\int_\Gamma e^{iz^2}\mathrm{d}z\right|\le\lim_{R\to\infty}{R\pi\over4}e^{-R^2\sin(2\xi)}=0\Rightarrow\...

f = @(x) sin(x); integral(f,0,pi) ``` 这将计算sin(x)在0到π之间的定积分值。 2. 使用字符串作为被积函数 如果被积函数比较简单,可以直接将其表达式以字符串形式传递给integral函数。例如: ``` integral('x^2',0,1) ``` 这将计算x^2在0到1之间的定积分值。 3. 高维积分 如果需要计算高...
