Determining the set of points at which the function is continuous.

  1. Feb 10, 2013 #1
    1. The problem statement, all variables and given/known data
    Determine the set of points at which the function is continuous.
    F(x,y) = arctan(x + √y)

    2. Relevant equations
    Perhaps the chain rule?


    3. The attempt at a solution
    I derived it, but the solution in the back of the book is nothing like what I expected. It involves e and other trig functions.
