Use the half-angleformula to rewrite ( ((sin))^2(t)) as ( (1-(cos)(2t))2).(∫ (1-(cos)(2t))2dt)Since ( 12) is constant with respect to ( t), move ( 12) out of the integral.( 12∫ 1-(cos)(2t)dt)Split the single integral into multipleintegrals.( 12(∫ 1dt+∫...
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...
