Web2 Answers Sorted by: 12 The result is trivial if x = 0, as we then have that x is a nonnegative real scalar multiple of y and we have equality. Assume x ≠ 0. Look carefully at the proof of the Cauchy-Schwarz inequality: Express y as α x + z, where x, z = 0. This can always be done by letting α = x, y x, x and z = y − α x. Then WebSep 29, 2024 · The only way a continuous nonnegative function can integrate over [ 0, ∞) to 0 is if it's 0 everywhere in that interval. Since e − x is nowhere 0, we must have ( f ( x)) 2 = 0, so f ( x) = 0. Let's see if I can make another method work:
