Hi ,(adsbygoogle = window.adsbygoogle || []).push({});

I have difficulty to find the folowing questions about limit computation.

IFlim xy/(x^2+y^2)( when (x,y)---(0,0))

Evaluate the limit as (x,y) approaches the origin along:

a) The spiralr=0, θ >0

b) The differentiable curvey=f(x),with f(0)=0

c) The arcr=sin(θ )

Thank you
