   1. The problem statement, all variables and given/known data
   f(x,y) = ([itex]x^{2}[/itex] + [itex]y^{2}[/itex])^-2
   [itex]x^{2}[/itex] + [itex]y^{2}[/itex] ≤ 2
   x ≥ 1
   
   2. Relevant equations
   
   
   
   3. The attempt at a solution
   -4[itex]\pi[/itex] ≤ θ ≤ 4[itex]\pi[/itex]
   secθ ≤ r ≤[itex]\sqrt{2}[/itex]
   are these the correct domain?

   The angles should be [itex]\frac{\pi}{4}[/itex] not [itex]4\pi[/itex] but that was probably a typo :) Other than that yupp :)
