Solve for t if 0<t<2pi
Note: both are less than or equal to .
Please help!!
I am not sure what I should do.

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.
