Definite Integral – The question tests the ability to evaluate a definite integral, which involves finding the area under the curve of the function from the lower limit to the upper limit.
Polynomial Integration – The integral involves a polynomial function (1 - x^2), requiring knowledge of basic integration techniques for polynomials.
Fundamental Theorem of Calculus – The solution applies the Fundamental Theorem of Calculus, which connects differentiation and integration, allowing for the evaluation of definite integrals using antiderivatives.
