WebApr 12, 2024 · A common trick also is to let the integral in question be I, and add it to itself to simplify things. For example, try computing: I = ∫2014 0 √2014 − x √x + √2014 − xdx. Doing a substitution u = 2014 − x and adding the resulting integral to original gives 2I = ∫20140 1dx. Another trick is geometry. WebFeynman proposed the following elementary argument.

"WebFeynman proposed the following elementary argument. Consider instead f ( y) := ∫ 0 ∞ sin x x e − x y d x, so we need f ( 0). Then differentiate under the integral sign: f ′ ( y) = − ∫ 0 ∞ e − x y sin x d x, and this is easily evaluated (integration by parts twice). As we know f ( y) → 0 as y → + ∞ we find f and our integral is f ( 0). " - Feynman trick integral
