1. The problem statement, all variables and given/known data Find the general solution for a nonhomogenous equation. y''+4y=3csc2t 2. Relevant equations 3. The attempt at a solution I simplified the equation to... y''+4y=(3)/(sin(2t)) Then I guessed... y=Asint+Bcost y'=Acost-Bsint y''=-Asint-Bcost Then I got... -Asint-Bcost+4Asint+4Bcost=(3)/(sin(2t)) Simplifies to... 3Asint+3Bcost=(3)/(2sintcost)) NOTE: Trig Identity: sin(2t)=2sintcost I am stuck and I am not even sure if I took the correct steps.
