Thread: Plot Eq. How to?

How you doing guys!

I was wondering if someone would help me on how can I plot this Eq.

a(t)=(t+2)[u(t+1)]-u(t-1)

Thanks in Advance and Greets from Mexico!!

Hi lorenzo!

Yeah, it's very difficult problem. We have to plot a function what contain a other unknown function as u(t).

Sorry since this is signals topic I made a wrong assumption.
Actually u(t) happens to be the step function.

1 |----->
|
--------------->t
0 1

If I understand well your step function jump at origin from 0 to 1. Therefore the function a(t) has two irregular point: t=1 and t=-1. You able to plot piece by pice such as [-inf -1], [-1 1], [1 inf]. During the intervals a(t) behaves as normal function.

So in this case I have to to do every step independently, but based on my step function right!
