    Does y*ln(y^2+x^2) Approach Zero as (x, y) Goes to (0,0)?

    Homework Statement (x,y)-->(0,0) y*ln (y2+x2) Homework Equations ! The Attempt at a Solution i've tried polar coordinates i end up with sinθ in it don't know how to proceed and I've taken several paths like y=0 , x=0 , x=y2 , x=y , x=y3 they all yeild zero Edit : is it...
