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

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

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

Problem on Analytic function

Sun, 03 Feb 2013 22:32:47 +0000

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
