Given the differential equation diff(c,t,1) + 2*c(t) = r(t) I want to isolate r(t)/c(t) assuming the initial conditions are 0. Can someone please explain how to do this?
syms c(t) r(t)
dc = diff(c,t,1);
laplace(dc + 2*c == r)

Hello,
As per my understanding of the problem I have attached a code. I have assumed a c(t).
syms c(t) r(t)
c(t)=t.^2+2.*t
dc= diff(c,t,1)
r(t)=dc+2*c
laplace(r/c)
Please refer to the this MATLAB Answer for some help. Also, please click on the documentation link for syms , laplace and diff for more information on these functions.
