Question 1
A rectangular membrane of dimensions 1m x 2m is initially displaced according to f(x,y) = x + y. Calculate A_11.
💡 Hint: Set up the integrals carefully and solve them step by step.
Question 2
Consider a two-dimensional membrane with non-zero initial velocity as well as initial displacement. How would you handle the calculation of A_nm and B_nm together?
💡 Hint: Think about the individual contributions of both conditions to the overall behavior.
