The outer boundary of a circle
Webb18. Think about how the cartesian variables x and y are bounded. If we have the equation. x 2 + y 2 = r 2 ⇒ x = ± r 2 − y 2 or y = ± r 2 − x 2. And x , y < r. Note that this last condition also insures that the above square roots are real. Then this gives you bounds for your double integral, choosing to integrate x first, WebbThe point which is marked as red is the center of both circles.
