2elpha2 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 12:13 4 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 03:07 2 回...

Integrate the equation. Since the integral of 1du is u, and the integral of cos(u) du is sin(u), the result is 1/4*(u - sin(u)) + c. Substitute u back into the equation to get 1/4*(2x - sin(2x)) + c. Simplify to get x/2 - (sin(x))/4 + c....
