    Hi ,

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

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

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

    a) The spiral r=0, θ >0

    b- The differentiable curve y=f(x), with f(0)=0

    c) The arc r=sin(θ )

    Thank you
