forget about this part,, That's why i m asking you, what does u4(t) in ODE?? u(t)laplace--->1/s,,right?? So what is laplace u4(t)??

:smile: yes we still talking about u4(t). u(t) is unit step function.

thank you Serena, u4 denoted as a unit step function. general piecewise (etc u(t-4)f(t-4) ) is easy to solve but power of function itselfs make it undone. Do you have any idea how we can deal with it?

Homework Statement could u help to find result? I don't know laplace of u^4(t)?? Homework Equations y''+4y'+5y=3u^4(t)+7(t*u(t)*δ(t-1) The Attempt at a Solution The only one i couldn t found is 3u^4(t),,
