Problem on Analytic function

I want to define analytic function E, which is a function to time, t, but when I want to plot out E(t), there is always a error, which is attached. Who can help me figure out what is the problem? t isrange(0,0.0625,30). thanks

Hi

I do not believe "e" is defined like that (perhaps "e_const" not even sure), have you checked the help function for the build in functions?
I expect to see something like exp(-t) tat should work

Good luck

Thanks for your reply.
when I change it to -2*t, it still doesn't work, so what is the problem for the "invalid lower bound error" enclosed in the attachment.

Hi

for the plot further down on the definition node tabs you need to define the plot limits of "t", I expect then something is wrong there, check the doc
