Integral of sin(x/2) by x: -2*cos(x/2)+C −2cos(x2) Integral Calculatorcomputes an indefinite integral (anti-derivative) of a function with respect to a given variable using analytical integration. It also allows to draw graphs of the function and its integral. Please remember that ...
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...
根据e^{ix^2}=\cos(x^2)+i\sin(x^2) ,我们可以发现两个积分的值是一样的: \int_{-\infty}^\infty\cos(x^2)\mathrm{d}x=\int_{-\infty}^\infty\sin(x^2)\mathrm{d}x={\sqrt{2\pi}\over2} \\ 本篇文章也随着这个答案而结束。编辑...
2、int()函数常用来计算被积函数的不定积分和定积分，而integral函数常用来计算复杂的被积函数的定积分。【int和integral求解对比】例如，计算下列积分：1）用int()函数求其定积分 >>syms x >>I=int(x^5*exp(-x)*sin(x),0,+inf)2）用integral()函数求其定积分 >>fun=@(x)x.^5.*exp(...
