Question

write down the general solution of the following diff. eqn. WITHOUT finding the arbitrary constants and the undetermined coefficients.

y''+6y'+13y=x*(e^-3x)*sin2x+x^2*(e^-2x)*sin3x

Answer 1

sorry don't have time to try work this crazy thing out :)

here is a resource though

Answer 2

thanks for your interest but i know how to solve undetermined coefficients question type. the problem is question says find the general solution without finding the arbitrary constants and undetermined coefficients. so simply it means the question have easy way to solve without wasting time with messy things :)
