The integral of interest is I_5 = ∫√((x² - 4)/x) dx, which poses challenges for straightforward substitution methods. The discussion highlights that the integral does not yield an elementary result, as confirmed by Wolfram Alpha. There is a suggestion that the expression might be misinterpreted, proposing instead the integral ∫(√(x² - 4)/x) dx for clarity. The undefined nature of the function at x = 0 is also noted. Overall, the complexity of integrating the square root of a fraction with a radical is emphasized.

$\textsf{Evaluate the function}$
\begin{align*}\displaystyle
I_5&=\int \sqrt{\frac{x^2-4}{x}} \, dx
\end{align*}

ok, I thought this would be a simple U subst, but nothing looks convienent

W|A gives a non-elementary result.
 
I presume when $x=0$ it is undefined:cool:
 
Are you sure you did not mean $\int \frac{\sqrt{x^2-4}}{x}\,\mathrm{d}x$?
 
Thread 'Problem with calculating projections of curl using rotation of contour'
Hello! I tried to calculate projections of curl using rotation of coordinate system but I encountered with following problem. Given: ##rot_xA=\frac{\partial A_z}{\partial y}-\frac{\partial A_y}{\partial z}=0## ##rot_yA=\frac{\partial A_x}{\partial z}-\frac{\partial A_z}{\partial x}=1## ##rot_zA=\frac{\partial A_y}{\partial x}-\frac{\partial A_x}{\partial y}=0## I rotated ##yz##-plane of this coordinate system by an angle ##45## degrees about ##x##-axis and used rotation matrix to...
