Thanks <3

hey I was trying to work on it more, is it by any chance something like this

hey so this is my rough sketch of the first and last part how exactly will i fit in the -2u(t-8) in this. I did it in paint lol :( I'm a total noob but in the process of learning more help will be appreciated

Thanks a lot, but I am confused on the 2u part. I can draw u(t-3) and u(t-5) but what is 2u? I'm used to u's

Any one? :(

Sketch the following signal u(t-3)-2u(t-8)+u(t-5) if it was u(t-3)+u(t-5) I'd be able to sketch it, but the 2u(t-8) is confusing me help me :( I can draw the first part u(t-3) how do I add the second to the graph and then the third

Guys I know how to solve the simple ones but this one has complex roots I have to find the zero input response (D-1)(D2+1)y(t)=(D2+2)f(t) y(0)=4 y'(0)=3 y''(0)=3 D2= D square. Y' = first derivative Y''= secondI know the roots are +1, j and -j But I don't know how to solve or...
