## Homework Statement

x*sin(sqrt(x^2+y^2))/sqrt(x^2+y^2)

find the domain of continuity

## Homework Equations

none

## The Attempt at a Solution

I found the domain, which is x^2+y^2 > 0 and since x^2 >= 0 and y^2 >= 0 therefore the domain is (-inf,0) (0,inf)

but the professor then asked for the "domain of continuity" and asked us to "carefully explain", i don't know how that is different from the domain i found.
