Taylor Polynomial of degree 2

Hi friends, I'm having trouble with this Taylor Polynomial question.

f(x,y)=arctan(x/y)

Using Taylor Polynomial degree 2, find a quadratic approximation to arctan(1/3) to 4 decimal places. Use a calculator to find the value of arctan(1/3) to 4 decimal places, and comment on your answers.

I can use formula to get Taylor Polynomial to degree 2 for f(x,y), but I supposed to do next? Normally the question should give something like (x,y)=(1.98,3.02) etc, so we would find a close integer and apply Taylor Polynomial. In this case, I have no idea what I should do.

Also, what does the question mean by comment on my answers? Does that mean compare my answer with real solution?

Thanks.
