Area enclosed between two symmetric functions across four quadrants:

Core Logic

The curves are symmetric across the axes. The region is enclosed between the unit circle x² + y² = 1$x^2 + y^2 = 1$ and the parabolas y = ±(1 - x²)$y = \pm(1 - x^2)$.

By symmetry, the area α$\alpha$ in the first quadrant is the area under the circle minus the area under the parabola from x=0$x=0$ to x=1$x=1$.

Step 1: Calculate the Area Components

Area of a circle quadrant with r=1$r=1$ is (π)/(4)$\frac{\pi}{4}$.

Area under the parabola:

Step 2: Evaluate the Total Area

Multiplying both sides by 9:

Comparing with 9α = βπ + γ$9\alpha = \beta\pi + \gamma$, we get:

Hence,

Symmetry helps divide the integration work by 4. Recognizing standard shapes (like a circle sector) allows you to bypass complex integration entirely for half of the problem.
