A。解析:对于\(\int x\cos xdx\),使用分部积分法,设\(u = x\),\(dv=\cos xdx\),则\(du = dx\),\(v=\sin x\)。根据分部积分公式\(\int u dv=uv-\int v du\),得到\(\int x\cos xdx=x\sin x-\int\sin xdx=x\sin x+\cos x + C\)。选项B中的换元法不适用于此积分。选项C中...
例如积分∫√(a^2-x^2)dx可通过三角代换x= asinθ实现简化,将根号转换为三角函数表达式。而当被积函数包含复合指数结构时,如∫e^x^2dx,虽然无法用初等函数表示,但通过变量替换t=x^2可将其转化为误差函数形式,进而借助特殊函数表完成计算。对于包含分式结构的复杂积分,倒代换法往往能化繁为简,例如对∫(x^4...
