F(-无穷,0)=0。得:A(B-pi/2)(C)=0. (2)由于:F(x,-无穷)=0,特别有:F(0,-无穷)=0。即:A(B)(C-pi/2)=0. (3)由于(1),(2),(3),并注意到0<=F(x,y)<=1,知道A、B、C都不为0,且解得:B=C=pi/2, A=1/(pi)^2. 解析看不懂?免费查看同类题视频解析查看解答...
不定积分∫x^2arctanxdx的求解方法如下: 首先,我们可以使用部分积分法对积分进行拆解。部分积分法公式为∫u*dv = uv -∫v*du,其中u和v分别表示两个可微的函数。 令u = arctanx,dv = x^2dx,我们可以求出du和v分别为du = (1 / (1 + x^2))dx和v = (1/3)x^3。 将这些值代入部分积分法公式...
[题目]--- is it from here to the bus stop? --- About half an hour’s walk.A. How long B. How farC. How often D. How soon
Under certain load conditions, it is usually difficult to identify the series arc fault because its current has the similar waveforms as the normal working current. In order to solve this problem, a time domain visualization convolutional neural network (TDV-CNN) is proposed based on a multi-...
