integrate(f,a,b,(x_2,x_3,...,x_n)) 即需要在上下限后加入后面其他变量的值。 比如对于下式的计算: \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))...
∫x2sin(x3)dx. Indefinite Integral of a Real-Valued Function: Let f be a real-valued function of x. If there exists a function F f(x)=F′(x),∀x, then F is said to be an anti derivative of f. The general form, i.e. F(x)+C, where C is any arbitrary constant (independ...

Integrate[Sin[x],x] Integrate[Cos[x],x] 运行这些代码,我们可以得到sin(x)和cos(x)的不定积分的一般形式。 3.求解多重积分 除了求解一维函数的不定积分外,Integrate函数还可以用于求解多维函数的不定积分。例如,我们可以求解二维函数的不定积分,代码如下: Integrate[x^2+y^2,x,y] 其中,x和y是自变量。
