integrate.dblquad(f,a,b,y_1,y_2) 其中f为被积函数,a、b是变量x的上下限,y_1、y_2是变量y的上下限。 注意,此处定义函数f时,y要在x的前面。 具体示例如下,计算二重积分(在数分书上随便找的一个): \iint_D\sin x^2\mathrm dx\mathrm dy\\ 其中D 是y=0、 x=\sqrt{\pi/2}、 y=x 所...
令√x = t,则x = t²,dx = 2tdt,则原积分变成2∫sin(t²)dt,上下限不变,再用欧拉公式sin(t²) = [e^(it²) - e^(-it²)]/2i原式= -i∫[e^(-t²/i) - e^(-it²)]dt= -i√i∫e^(-t²/i) d(t/√i) + √i∫e^(-it²) d(t√i)= -i√i∫e^(-u...
