Find the limist if it exists for a 3-variable function

  1. Oct 2, 2009 #1
    1. The problem statement, all variables and given/known data
    lim(e^(-x*y) * sin( pi * z/2) as (x,y,z) approaches (3,0,1)

    2. Relevant equations



    3. The attempt at a solution
    i know how to find the limit exists or not for a 2-variable function which is just set x=o;y=0;x=y
    how can this method applies here

    Remember that the first approach when computing any limit is to just substitute the point that you are approaching.

    And think about whether the function is continuous there, right?
