WebSolving this for the wave equation gives the characteristic coordinates ξ = x + c t and η = x − c t. Then, with lots of chain rule (easy, but tedious), this change of coordinates will eventually lead you to the canonical form ∂ 2 u ∂ ξ ∂ η = 0. Integrating twice yields u = ∫ f ( ξ) d ξ + g ( η) = F ( x + c t) + g ( x − c t). Share Cite Follow WebSep 12, 2024 · A wave function is any function such that f(x, t) = f(x − vt).
