For the transverse wave equation

y = A \sin(\pi x + \pi t)

, choose the correct options at t = 0 a. points at x = 0 and x = 1 are at mean positions b. points at x = 0.5 and x = 1.5 have maximum accelerations c. points at x = 0.5 and x = 1.5 are at rest d. the given wave is travelling in negative x-direction
