## unit step function Archives

Solution: Using step function notation, f (t) = u(t − 1)(t2 − 2t +2). Completing the square we obtain, t2 − 2t +2 = (t2 − 2t +1) − 1+2 = (t − 1)2 +1. This is a parabola t2 translated to the right by 1 and

## Differential Equations

L [ u ( t − 1)] = e − s s , L [ u ( t − 4)] = e − 4 s s. With each of these Laplace functions found, I then put it all together back in the original equation, and simplified. 7 s − 1 s 2 ∗ e − s s
