Signal is periodic or aperiodic

[vead]

Hello
I need help to find out the type of signal. Whether it is periodic or aperiodic signal. Periodic signal which repeats over and over with repetition period of T

I can find out time period T but I don't understand it's is periodic or a periodic signal

periodic. since t is not limited.

Don't you know that all trig functions are periodic? Plot it out and see.

Please assist us in this task.

A better answer would be to get vead to tell us the difference as he understood it between periodic an aperiodic signals and then to ask him to apply this to his case.

I agree. Just like how we answer questions like this periodically until a time limit is imposed then it is no longer periodic. Get the hint @vead?

I agree but I am not asking the exact answer. Main problem is that, if question is given for periodic or a periodic signal then I can solve the question ie I did in my first post. I can put the value in formula and can find out the time. I am asking in practical way.
DC source that generates DC signal
1A current flowing from the DC power supply for 1 minute. Does it means that the current will be same for every time. For 1,2,3 minutes the value of current will be 1A. Is that a periodic signal

not
