Integrate ∫sin3(x)cos2(x) dx. Integration: We have an indefinite integral whose integrand contains a sine and a cosine function. We will apply the substitution method to evaluate this integral. We will substitute a constant of integration at the end. Answer and Explanation: Given:...
Tracing antideriv indicates that Maxima is computing the antiderivative and computing the limits and getting the limits incorrect. Presumably, the wrong branch is taken. We have something similar for integrate(log(sin(x)),x,0,%pi/2). rtoy added bugs integrate sourceforge labels Jul 7, 2024 ...
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\...

\int_0^1\sin x\cos y\tan z\ \text{d}y\quad x=2,\ z=3\\ 可以这样写: def f(y,x,z): return np.sin(x)*np.cos(y)*np.tan(z) print(integrate.quad(f,0,1,(2,3))) 这里需要注意的是quad只会计算函数f第一个变量的积分。 2.“向量值函数”积分 为什么这里要打引号呢?因为SciPy...
