(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

[itex]\int \frac{\sqrt{9 - x^2}}{x} dx[/itex]

2. The attempt at a solution

x = 3sin(u)

dx = 3cos(u)du

u = arcsin(x/3)

[itex]\int \frac{3\sqrt{cos(u)^2}}{3sin(u)} 3cos(u)du[/itex]

[itex]3 \int \frac{cos(u)}{sin(u)} cos(u)du[/itex]

Don't really see anywhere to go from here. Apologies if the work is hard to follow, I cut out a few steps because inputting equations is a real pain in my opinion.
