Step 1: Identify the integral you need to evaluate: ∫_0^1 (1 - x^2) dx.
Step 2: Break down the integral into two parts: ∫_0^1 1 dx and ∫_0^1 -x^2 dx.
Step 3: Calculate ∫_0^1 1 dx. This is simply the area under the curve from 0 to 1, which equals 1.
Step 4: Calculate ∫_0^1 -x^2 dx. The antiderivative of -x^2 is -x^3/3.
Step 5: Evaluate the antiderivative from 0 to 1: [-x^3/3] from 0 to 1 = [-(1^3)/3 - (0^3)/3] = -1/3.
Step 6: Combine the results from Step 3 and Step 5: 1 + (-1/3) = 1 - 1/3 = 2/3.
Step 7: Write the final answer: ∫_0^1 (1 - x^2) dx = 2/3.
