3. [5 pt] Which of the following expressions correspond to the travelling waves? Explain why using the 1-dimensional wave equation. (a) = A cos(kx – wt) (b) y = A cos(kx – wt) sin(kx + wt) (c) y = A cos(kx – wt) + B sin(kx + wt) (d) Y = A(ax– bt?) The quantities A, B, a, b, k, and w are all positive constants. = - = )
