    Evaluating A Limit

    Can anyone guide me as to how I would evaluate this limit

    lim as (x,y) -> (0,0) of ( (x^2 + y^2)^(1/2) x ln(1/(x^2 + y^2)^(1/2))

    i plugged in several paths and the limit was 0 for all of them but I am required to do it the delta epsilon way

    I would switch to polar coordinates and find the limit as r goes to zero.

    Please improve your notation, you appear to be using "x" as a variable and as a multiplication operator.
