(D^2-1)y=Cosx

#higherorderlineardifferentialequation #mathspulse #chinnaiahkalpana Hello, People! Here is the video of solving higher order linear differential equation problem, whose Q is in Sinax or Cosax form. Please have some patience and watch till end😊. My hearty thanks to all the subscribers, viewers, supporters and well-wishers❤ With Love, Chinnaiah Kalpana🍁 Note: f(x)= Sinax or Cosax If f(x)=Sinax or Cosax, then Particular Integral is given by P.I. = [1/Φ(D)]Sinax (or) Cosax. In Φ(D) replace D^2 by -(a^2), provided Φ(D)≠0. If Φ(D)=0, when we replace D^2 by -(a^2), then P.I. = x[1/Φ'(D)]Sinax (or) Cosax. Again replace D^2 by -(a^2) in Φ'(D) provided Φ'(D)≠0, then P.I.=x^2[1/Φ"(D)]Sinax (or) Cosax. This process may be repeated if Φ"(D)=0 and so on.
