WebApr 5, 2024 · 1 Answer. As the integral ∫ − a a f ( x) d x of an odd map is always equal to zero, and the two given formulas also vanish for odd maps, what you discovered for odd monomials is normal. While the two formulas are valid for constant maps, they are not exact for x ↦ x 2. The second one is wrong for x 2 also: ∫ − 1 1 x 2 d x = 2 / 3 ...
