• ln^2 (x), ln (x)^2 — \ (\ln^2\left (x\right)\) 分步积分计算器。 输入和解释方便！

进行约分: f’(x)=lim dx->0 2x+dx 因为dx是一阶无穷小，所以f’(x)=2x 以上就是x^2导数的严格求导过程，我相信题主能看明白，谢谢

标题格式原因，其实本文要讲的是 \int_ {0}^ {+\infty}e^ {-x^2}dx 的积分方法。 第一种：转换为二重积分记 I = \int_ {0}^ {+\infty}e^ {-x^2}dx 那么同理 I = \int_ {0}^ {+\infty}e^ {-y^2}dy 两者相乘得 …

Skip the f (x)= part and the differential dx! The Integral Calculator will show you a graphical version of your input while you type. Make sure that it shows exactly what you want. Use …

dx 是一个微变，表示一个很接近零的常数，其就是 Δx 的极限值。 我们先看一阶微分的定义。 很显然分母 dy 是 d 算符对 y (x) 函数的一个运算，得到 dy 这个新函数；而 dx 只是 Δx 的另一种 …

For example, you can express $\int x^2 \mathrm{d}x$ in elementary functions such as $\frac{x^3}{3} +C$. However, the indefinite integral from $(-\infty,\infty)$ does exist and it is …

I'm trying to find $\int x^x \, dx$, but the only thing I know how to do is this: Let $u=x^x$. $$\begin{align} \int x^x \, dx&=\int u \, du\\[6pt] &=\frac{u^2}{2}\\[6pt] &=\dfrac{\lef...
