S(x) = ∫₀ˣ sin(πt²/2) dt
C(x) = ∫₀ˣ cos(πt²/2) dt
Cara Pakai
Enter a value of x and the tool computes the Fresnel sine integral S(x) and cosine integral C(x) using high-precision numerical integration. Fresnel integrals describe near-field diffraction and also define the clothoid (Euler spiral) used in road and railway transition curves, so the calculator serves both optics work and civil-engineering study.
