SUMMARY
The discussion focuses on determining the coefficients p and q in the superposition of solutions for the differential equation y'[t] + 9.7 y[t] = 3 E^(-0.4 t) Cos[t] with initial condition y[0] = 3. The solutions y1[t] and y2[t] are derived from the equations y'[t] + 9.7 y[t] = E^(-0.4 t) Cos[t] and y'[t] + 9.7 y[t] = 0, respectively. By substituting y[t] = p y1[t] + q y2[t] into the original equation, one can derive a solvable equation for p and q.
