I'm working on a computer programming project on matlab,(adsbygoogle = window.adsbygoogle || []).push({});

and need an equation in the form of y'' + y' + y = 0 or k or inthe form of y' + y = 0 or k..

everything will be simple for me after that

but I have these two equations

N - ay'' - by' - cy - dx'' - ex' - fx = 0

M - gy'' - hy' - iy - jx'' - kx' - lx = 0 where a,b,c,d,e,f,g,h,i,j,k,l are constants N,M=c sinwt and y(0)=x(0)=y'(0)=x'(0)=0

can you propose me method to be able to arrange these. I didn't deal with diff. eqns . more than 3 years, I may need some help to remember,

if you can help, plz do so, I don't have much time :(
