lesson(261 Superposition (The Backbone of linear system) o @ This technique is used to scive linear IBUPS. (c.e. The PPE and Bes should be linear) The procedure: break the IBup into subproblems, thes, Salve each subpart individually, and their add the results of each part. PDF! Ex-i consider The IBUPS u = Uxx + f(x,t; aste (1</ Best wat oo too t=0 fc:UX, 01 - P(X); Osxsd To solve cih, break the IBUPL into two parts: You candt use separation of variables to ) Snce the pos is nonhomog. solvec) و ) land مدار IBUP PDE: Ut=C2x + $(x, ki Be's fula,t=0 otro ulb, b=0 PDG.
