You explained more in 2:15 than I learned in the past month. Thank you! Exam is in less than 10 hours…

Understood the concept finally.Thank you.

The interesting thing to me is how if you convert the answer back with inverse laplace it becomes t^2*u(t-1). Is this supposed to happen?

[ranjithravichandran]

In case of L{(t-1)^2 u1 (t)}. How can I do

[kamalkishoremahato]

Sir why u put t^2 in 1st step..can u explain it??

I’m stuck on my homework problem it is L{(t-1)^(3)e^(t)u(t-1)}
