Any of the two functions must be easily differentiable to apply the formula. Answer and Explanation: Given: $$\int x^2\ln x\text dx $$ Let us take $$\begin{align} u&=\ln x\\ v&=x^2 \end{align} $$ Then the integral becomes $$\begin{align} \i......
【解析】解因为∫_0^(+∞)x/(1+x^2)dx=1/2ln(1+x^2)∫_0^(+∞)=lim_(x→+∞)1/2ln(1+x^2 所以∫_0^(+∞)x/(1+x^2)dx 发散,从而 ∫_(-∞)^(+∞)x/(1+x^2)dx 发散注意∫_(-∞)^(+∞)x/(1+x^2)dx≠lim_(b→+∞)∫_(-∞)^bx/(1+x^2)dx相...
