How many solutions does the pair of equations y = 0 and y = โ5 have? WebApr 11, 2024 ยท The string will then vibrate according to the wave equation โ 2 u/โt 2 = 2 2 ... To summarize separation of variables, we first assume that the solution u is equal to a product of functions that only depend on each of our variables. Next, we move expressions involving each variable to opposite sides of an equality and set those expressions ...
