we cant just force the shift , if we had t^2H(t-1)
then to shift the quadratic we would (t-2+2)^ then we would expand
(t+2)^2 to t^2+4t+4 then take the laplace transform of that .
um i dont know my teacher never really talked about it like that,
ur prolly right , and another thing i cant see what ever u typed in those black boxes
my computer wont let me so its hard for me to tell what ur doing .
im sure ur right , but my teacher told us to take the laplace tranform
of a function time the heaviside function
he said the function needed to have the same shift as the heaviside
function in order for the formula to work .
f(t)H(t-1) = e^(-s)*L(f(t))
