WebThe functions V (x, t) and eta (x, t) that satisfy the pair of differential equations above. To be able to find solutions to this problem, you need to be given: V (x, 0) = V0 (x) and eta (0, t) = eta0 (t) Assume your domain is [0, L] X [0, T], where x in [0, L] and t in [0, T]. WebJan 28, 2024 · The first step is to transform the second order equation to a set of two coupled first order equations. Define an auxiliary function u ( T) = d r ( T) d T. This results in the system d u d T = k − ( 1 − 5 r) ( 3 + 2 r 2) …
