integrate(x*(cos(x/2)),x) and f(n):=expand(integrate(x*(n+cos(x/2)),x)-integrate(n*x,x)); are same function but... When n are even numbers, results are always 1/2(%i2) f(1); (%o2) 2*x*sin(x/2)+4*cos(x/2) (%i3) f(2); (%o3) x*sin(x/2)+2*cos(x/...
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 ...
\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...
