$$\int\limits_{0}^{1} x \operatorname{asin}{\left(\frac{1}{x} \right)}\, dx$$

Integral(x*asin(1/x), (x, 0, 1))

Detail solution

Use integration by parts:

$\int \operatorname{u} \operatorname{dv} = \operatorname{u}\operatorname{v} - \int \operatorname{v} \operatorname{du}$

Let $u{\left(x \right)} = \operatorname{asin}{\left(\frac{1}{x} \right)}$ and let $\operatorname{dv}{\left(x \right)} = x$ .

Then $\operatorname{du}{\left(x \right)} = - \frac{1}{x^{2} \sqrt{1 - \frac{1}{x^{2}}}}$ .

To find $v{\left(x \right)}$ :
1. The integral of $x^{n}$ is $\frac{x^{n + 1}}{n + 1}$ when $n \neq -1$ :
  
  $\int x\, dx = \frac{x^{2}}{2}$
Now evaluate the sub-integral.
The integral of a constant times a function is the constant times the integral of the function:

$\int \left(- \frac{1}{2 \sqrt{1 - \frac{1}{x^{2}}}}\right)\, dx = - \frac{\int \frac{1}{\sqrt{1 - \frac{1}{x^{2}}}}\, dx}{2}$
1. Don't know the steps in finding this integral.
  
  But the integral is
  
  $\begin{cases} \sqrt{x^{2} - 1} & \text{for}\: \left|{x^{2}}\right| > 1 \\i \sqrt{1 - x^{2}} & \text{otherwise} \end{cases}$
So, the result is: $- \frac{\begin{cases} \sqrt{x^{2} - 1} & \text{for}\: \left|{x^{2}}\right| > 1 \\i \sqrt{1 - x^{2}} & \text{otherwise} \end{cases}}{2}$
Now simplify:

$\begin{cases} \frac{x^{2} \operatorname{asin}{\left(\frac{1}{x} \right)} + \sqrt{x^{2} - 1}}{2} & \text{for}\: \left|{x^{2}}\right| > 1 \\\frac{x^{2} \operatorname{asin}{\left(\frac{1}{x} \right)} + i \sqrt{1 - x^{2}}}{2} & \text{otherwise} \end{cases}$
Add the constant of integration:

$\begin{cases} \frac{x^{2} \operatorname{asin}{\left(\frac{1}{x} \right)} + \sqrt{x^{2} - 1}}{2} & \text{for}\: \left|{x^{2}}\right| > 1 \\\frac{x^{2} \operatorname{asin}{\left(\frac{1}{x} \right)} + i \sqrt{1 - x^{2}}}{2} & \text{otherwise} \end{cases}+ \mathrm{constant}$

The answer is:

$\begin{cases} \frac{x^{2} \operatorname{asin}{\left(\frac{1}{x} \right)} + \sqrt{x^{2} - 1}}{2} & \text{for}\: \left|{x^{2}}\right| > 1 \\\frac{x^{2} \operatorname{asin}{\left(\frac{1}{x} \right)} + i \sqrt{1 - x^{2}}}{2} & \text{otherwise} \end{cases}+ \mathrm{constant}$
