If given functions are {eq}f(x),g(x) {/eq} then {eq}\displaystyle \int f(x)g(x)dx = f(x)\int g(x)dx - \int f'(x)(\int g(x)dx)dx {/eq} Formulas used: {eq}\displaystyle \int \sin x dx = -\cos x {/eq} {eq}\displaystyle \frac{dx^n}{...
Evaluate: ∫sin2xdx. Integration Of A Function: Integration is the inverse process of differentiation. Consider a function g such that g(x)=G′(x), then ∫g(x)dx=G(x)+C. Useful Formula: cos2x=1−2sin2xsin2x=1−cos2x2. Answer and Explanation: Let I=∫...
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主总是能出一些让我眼前一黑的积分 2022-01-...

Find the indefinite integral {eq}\int sin^3(x) cos^2 (x) dx. {/eq} Indefinite Integral: The given integral is indefinite integral (without any limits) and has given in the form {eq}\int f(g(x))g'(x)dx {/eq}. The easiest technique of integration to solve all those integrals ...
Indeed, plotting the graph of fn)fn) on [1,π][1,π] and 201≤n≤264201≤n≤264 gives which clearly demonstrates the chaotic behavior as in the logistic map. This can also be glimpsed by the fact that the iteration t↦sin(xt)t↦sin(xt) resembles th...
