Evaluate {eq}\displaystyle \int \sin (2x)\cos (2x) \ dx {/eq} Integration by Substitution: Integration by substitution can be used when one part of our integral is the derivative of the other portion. We recall the substitution rule for integration: If {eq}u=g(x) {/eq} is a d...
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...
