WebNov 17, 2024 · The wave equation solution is therefore u(x, t) = ∞ ∑ n = 1bnsinnπx L sinnπct L. Imposition of initial conditions then yields g(x) = πc L ∞ ∑ n = 1nbnsinnπx L. The coefficient of the Fourier sine series for g(x) is seen to be nπcbn / L, and we have nπcbn L = 2 L∫L 0g(x)sinnπx L dx, or bn = 2 nπc∫L 0g(x)sinnπx L dx. General Initial Conditions WebAug 27, 2024 · where Δs is the length of the segment and ¯ x is the abscissa of the center of mass; hence, x < ¯ x < x + Δx. From calculus, we know that. Δs = ∫x + Δx x √1 + u2 x(σ, t)dσ; however, because of Equation 12.2.2, we make the approximation. Δs ≈ ∫x + Δx x 1dσ = Δx, so Equation 12.2.4 becomes. WebNov 17, 2024 · ρ Δ x u t t = T ( u x ( x 2, t) − u x ( x 1, t)). Dividing by Δ x and taking the limit Δ x → 0 results in the wave equation u t t = c 2 u x x, where c 2 = T / ρ. Since [ T] = m l / t 2 and [ ρ] = m / l, we have [ c 2] = l 2 / t 2 so that c has units of velocity. different parts of a mountain bike
