What is the Integral of tan^5(x) dx? If integral from {0} to {6} of f(x) dx = 10 and integral from {0} to {4} of f(x) dx = 7, what is \integral from {4} to {6} of f(x) dx ? Find the indefinite integral. Integral of (-cos x)/(sin^8 x) dx. If integral_...
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...
