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...
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...
Integral of cos(2*x) by x: sin(2*x)/2+C sin(2x)2 Draw graph Edit expression Direct link to this page Value at x= Integral Calculator computes an indefinite integral (anti-derivative) of a function with respect to a given variable using analytical integration. It also allows to ...
For instance, it is known that ddxsin(x)=cos(x) and, therefore, one antiderivative of cos(x) is sin(x). A note to say that typically the general antiderivative involves a + c term at the end since the derivative of a constant is zero. The antiderivative of cos(x) can be...
