\[\int\limits\limits_{}^{}\frac{ \arcsin(x) }{ x^2 } dx\]
I have no idea... I am think about trig substitutions but I am not sure about this...
Not sure either, but what does \(x=\sin(u)\) get you?

Why would you do that?
I was thinking about trying integration by parts... have you tried that yet? :)
It would get rid of the arcsin.
It's just a guess
Well I was going to make a substitution and then use intergration by parts but I am not sure...
What if I said u=arcsin(x) ?
That's the same as x = sin(u)
Right. But if I said that I would get a squart root and I could use trigonometric substitution.
Allright so I so far got... Use intragtion by parts: u=arcsinx) \[du=\frac{ 1 }{ \sqrt{1-x^2} }\] dv=x^-2 dx v=-x^-1
\[\frac{ -\arcsin(x) }{ x }-\int\limits_{}^{}\frac{ 1 }{ x \sqrt{1-x^2} }dx\]
I am kinda stuck at this point.
First do the substitution $$x=\sin(u)\implies dx=\cos(u)du$$ then $$\int \frac{\arcsin{x}}{x^2}\;dx=\int \frac{u\cos(u)}{\sin^2(u)}\;du=\int u\csc(u)\cot(u)\;du$$ $$\int u\frac{d(-\csc(u))}{du}du$$ do the integration by parts
Hmm let me see...
@BAdhi So I got to this point \[\int\limits_{}^{}ucsc(u)\cot(u) du\]
I would use integration by parts here right?
we know that $$\frac{d\csc(u)}{du}=-\csc(u)\cot(u)$$ then, $$\begin{align*}\int u\csc(u)\cot(u)\,du&=\int u\frac{-d\csc(u)}{du}\,du\\ &=-u\csc(u)+\int \csc(u)\,du \end{align*}$$
Yep I got that far.
Now I need to figure out the integral of csc(x).
Thanks I got this :) .
could use x = sin(u)
Thank you too wio :) .
