SUMMARY
The function D=A sin(kx) cos(ωt) is analyzed to determine if it satisfies the linear wave equation. To verify this, one must compute the second partial derivatives of D with respect to x and t. The relationship between wave velocity and wave number is defined as v = ω/k. If the function adheres to the linear wave equation, it will exhibit the fundamental characteristics of linear waves.
