Hi all, I'm having trouble understanding a basic concept introduced in one of my lectures. It says that: To solve the DE [tex]y(t) + \frac{dy(t)}{dt} = 1[/tex] where [tex]y(t) = 0[/tex], using the Euler (forward) method, we can approximate to: [tex]y[n+1] = T + (1-T)y[n] [/tex] where [tex]T[/tex] is step size and [tex]y[0] = 0[/tex]. I have no idea how this result is obtained, the only thing they say is that in general for [tex]\frac{dx_1}{dt} = \frac{x_1[n+1] - x_1[n]}{T}[/tex] for [tex]t = nT[/tex]. Can anyone please help me understand how they arrived at the solution for [tex]y[n+1][/tex]? Thanks!
