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

[SneakyG]

Homework Statement

Determine the set of points at which the function is continuous.
F(x,y) = arctan(x + √y)

Homework Equations

Perhaps the chain rule?

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.
