How can I find asymptote of the following function ?

$y=x^{3}y^{2} - \sin(x)$

Is there a way except finding $y$ directly ?

    $\begingroup$ Intuitively, if $x$ is very large, $y$ has to be very small to make $y-y^2x^3=\sin x$. $\endgroup$ – Arthur Dec 4 '16 at 9:41

  • $\begingroup$ @ Ivan Neretin: ys i know.. i can calculate y in terms of x but i want to know if i can find the asymptote without finding y. $\endgroup$ – Suman Samadder Dec 4 '16 at 17:21
