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...
第一个注意到分母可以变成【3+cos(2x)】/2而正好sin(2x)dx=-dcos(2x)/2题目就转化为-∫dcos(2x)/【3+cos(2x)】 2022-01-23 12:134回复 晓之车高山老师 其实up表达的意思就是,被积函数某个地方稍有改动,对应不定积分表达式就可能有很大的变化,甚至完全不同 2022-01-24 03:072回复 QNのstarlake up主...
