I prefer Euler substitutions
Here second Euler substitution work nice
sqrt(x^2+1)=xu-1
In this integral trig substitution is a good option
Calculate integral
Int(1/(x^2(4x^2-3)^2sqrt(x^2-1)), x)
with trig sub and Euler substitution
(trig substitution with secant and first Euler substitution sqrt(x^2-1)=u-x)

I actually just left a class about this exact subject. lol. Thanks
btw, I just now, after a few months watching your videos, noticed that you are mirror writing. that's impressive.
