what is the steps for calculating lim (x,y)->(1,3) [arcsin(3xy-9)/arctan(xy-3)]
i know how to do it in 1 dimension..if let z=xy. can i actually do this?
my solution is 3
actually how to use [tex] code in this forum?
i am new here
thanks!

You would just say something like
Let $\displaystyle z=xy$. So if $\displaystyle (x,y) \to (1,3)$, then $\displaystyle z \to 3$.
Therefore:
$\displaystyle \lim_{(x,y)\to(1,3)} \frac{\arcsin(3xy-9)}{\arctan(xy-3)} = \lim_{z \to 3} \frac{\arcsin(3z-9)}{\arctan(z-3)} = \cdots$
You could continue solving the limit using standard one variable techniques.
