Apply the sin ^2 x power-reducing formula sin ^2x= (1-cos 2x)2.\begin{split}\int \sin ^{4}x\d x&=\int (\sin ^{2}x)^{2}\d x\\&=\int \left (\dfrac {1-\cos 2x}{2}\right )^{2}\d x\\&=\int \left (\dfrac {1-2\cos 2x+\cos ^{2}2x}{4}\right )\d x\...
这是同一被积函数的两种不同分解. 缺省时,Sin[x] 和Cos[x] 项均被包括在内:In[19]:=Out[19]=在设置为 "AdditiveTerm"->Sin[x] 时,Sin[x] 项不被包括在检测到的内核中:In[20]:=Out[20]=我们可以看到如何使用 "LevinFunctions" 选项将函数组包括在被积函数中或从被积函数中排除....
2 3 %i %pi %pi log(4) (%o2) ───────── - ────────── 2 4 This is incorrect since cos(x) >= 0 over the integration range, so the integrand is always real. The actual value of the integral is -%pi*log(2)/2, which we have. The imaginary part should ...
仅附加 ‘cos’ 或‘sin’ 权重和无限积分限制,它包含 infodict[‘ierlst’] 中代码的解释 其他参数:: epsabs:float 或 int,可选 绝对容错。默认值为 1.49e-8。quad试图获得准确度abs(i-result) <= max(epsabs, epsrel*abs(i))其中i= 积分函数从a到b, 和result是数值近似。看埃普雷尔以下。
