Hello everyone,(adsbygoogle = window.adsbygoogle || []).push({});

i have this question and not even sure how to approach it:

[tex]\frac {di}{dt}+4i+3\int_{0^-}^t{i(z)dz = 12(t-1)u(t-1) [/tex]

and [tex]i(0^-) = 0[/tex]

find [tex] i(t) [/tex]

last topics we covered were laplace transforms (and inverse) and dirac delta function.

At least some hint to get me started would be a great help.

EDIT:

oh, and again u(t) = 1 for t >= 0 and u(t) = 0 elsewhere.
