1. ## Integration problem help please???

Integral of (sqrt(2x^2-3))/x^2

Can someone please help me with this problem? I've stared at it and tried to figure it out for half an hour now to no avail.

Thanks.

2. Are you trying to say $\int \frac{\sqrt{2x^{2 - 3}}}{x^2}$
or $\int \sqrt \frac{{2x^{2 - 3}}}{x^2}$

Try trig substitution:

Let $x=\frac{1}{\sqrt{6}} \sec \theta$, then $6x^2-1 =\sec^2 \theta -1= \tan^2 \theta$

Then $\int \frac{\sqrt{2x^2-3}}{x^2}= \int \frac{\sqrt{\frac{1}{3}(6x^2-1)}}{x^2}=...$
