This is a partial differential equation, and we can use separation of variables to find its general solution. Let's assume that the solution is of the form u ( x, t) = X ( x) T ( t). Substituting this into the equation, we get: X ″ ( x) T ( t) = 1 2 X ( x) T ′ ( t) Dividing both sides by X ( x) T ( t) and rearranging ... rei shipping canada
