Circular and simultaneous inequalities (HSC SSCE Mathematics Extension 1): Flashcards

They describe regions inside or outside a circle.

$(x - h)^2 + (y - k)^2 < r^2$ describes the interior.

It describes points outside the circle.

$(x - h)^2 + (y - k)^2 = r^2$ is the boundary.

It shows shaded areas where inequalities apply.

Finding overlaps of $y < 1 - x^2$ and $y > x - 1$.

They model network coverage and spatial planning.

Use test points to ensure shading is accurate.

It shows points less than 3 units from the center.

It helps quickly visualize and find solutions.
