using LeHopital Rule ==> lim 3sin(3t) = 0
left hand side is infinity, right hand it negative infinity

i tried that site but i want mathematic process. not the graph one.
that was a little while for me to tell you mathematically, but i know if you look at the graph and imagine when t get close to zero, you'll is it gets to a very small number or a big number. it depends which way you look it it
