Lim (x^2-4y^2)/(x+2y) as (x,y)->(-2,1)

    lim (x^2-4y^2)/(x+2y) as (x,y)->(-2,1)
    Does this limit go to -4 or DNE since it is undefined all along x+2y?

    Re: Limit

    You mean x+2y=0, right? You seem to know exactly what the problem is. My inclination is to say, no, does not exist. But you might want to look up the exact phrasing of the definition of limit to be sure. Then you'll be prepared to defend it in court.
