Your answer is incorrect. Given y(4) - 9y" - 81y" + 729y' = t² + 1+ tsint, determine a suitable form for Y(t) if the method of undetermined coefficients is to be used. Do not evaluate the constants. A suitable form of y(t) is: Y(t) Aot² + A₁t+ A₂+ (Bo + B₁t) cost + (Co + C₁t) sin t

Choose one t(Aot² + A₁t + A₂) + Bot cost + Cot sin t t(Aot + A₁) + Bo cost + Co sint t(Aot² + A₁t) + Bo cost + (Co + C₁t) sint t(Aot² + A₁t + A₂) + (B₁ + B₁t) cost+ (Co + C₁t) sin t t(Aot + A₁) + (Bo + B₁t) cost+ (Co + C₁t) sint Aot² + A₁t+ A₂ + (Bo + B₁t) cost+ (Co + C₁t) sin t Aot² + A₁t+ A₂2 + Bo cost + Co sin t Aot+ A₁+ Bot cost + Cot sin t
