    Is it something like sin t = .5  or something?

    e^-1 cost +sint(-e^-t)=0

    Do you mean
e^-t cost + e^-t sint = 0?
If so, factor out the e^-t and you have
e^-t (cost - sint) = 0
e^-t is never 0, so that leaves
sint = cost
or
tant = 1
I think you can work with that, eh? Remember all four quadrants.
