SUMMARY
The discussion focuses on solving the wave equation using coefficient equations, specifically through the substitution of second differentials into the wave equation. The equation A''(x) + (w/v)^2A(x)sin(wt)=0 is derived, leading to the conclusion that A''(x) = -k^2 A(x), where k is defined as k(n) = nPI/L, with n being a quantized integer. The normal mode frequencies are expressed as w(n) = nPI/L * v. The participants seek clarification on the implications of these results, particularly regarding the relationship between wavelength and string length for part (b) of the problem.
