# Unit Step function 2 -Maths watch

1. Hello,

Does anyone know how to draw the following unit step function, and how would it look like.

e^t u(t)

and u(t) - u(t-1) + u(t-2)

and u(t-1)

for u(t) = {1, t>= 0
{0, t< 0

thanks a lot.

Do you want to explain this properly? I don't have a clue what you're talking about.

Basically I have to draw a Unit Step Function curves,
A unit step curve is discontinious ie it breaks up, into horizontal lines.

For the question, the Step unit is defined by,

u(t) = {1, t>= 0
{0, t<0

And I need to sketch the following curves for it

e^t u(t) u(t) - u(t-1) + u(t - 2) and u(t - 1)

Are u able to sketch these curves

thanks

I think so, if I understand your question correctly.

Ok, I assume you can draw u(t). From this you should be able to dedcue immediately e^t u(t) (why is this obvious?) and u(t-1) and u(t-2) and combining the graphs, you should be able to draw all the required graphs.
