Limit computation

  1. Oct 13, 2005 #1
    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
    B

    Have you tried converting your expression to polar?

    Have you yet done any work on the problem? There should be at least one thing you can do that is very clear...
