I have no idea at all really what is it you are trying to do,
In what you wrote, ft is just a list of numbers. So you are asking solve to do this solve(list_of_numbers==0,t).
But if you are trying to find solution to exp(x)==0 then there is no solution.
What value of 't' you think will make exp(sin(t)) zero? sin(t) is between 1 and +1. So, just plot exp() between these 2 values and you'll see it is not zero.
You have to go to infinity and beyond to have any luck of making exp() in the limit go to zero.
