1.2.2.2 Finding Limits in several variables

https://mathematica.stackexchange.com/landing/r/digest?cta=question&id=21544

Is there a way to find a limit of a multivariable function, like

\[\lim _{(x,y)\to (0,0)} f(x,y)\]

with Mathematica?

When \(f\) is continuous, we can use

\[\lim _{(x,y)\to (0,0)} f(x,y)=\lim _{(x,0)}\]
