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 12:134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star...
∫sin2(x)cos(x)dx (Use C as the arbitrary constant.) U-Substitution:One of the many different integration methods is u-substitution. As its name suggests, it employs the variable u as a transient substitute. An appropriate substitution could possibly convert th...
