    differential equations

    Use Laplace Transforms

    Y(t) + 4y(t) = f(t) with y(0) = 1, y(0) = 1, where
    f(t) = { 4t, 0 < t < 1
    { 4, t > 1

    Re: differential equations

    can you explain what you've tried so far please,

    anyway here's the first thing you can do,

    write f(t) as a function of unit step

    f(t)=4t[u(t)-u(t-1)]+4u(t-1)
