## Homework Statement

(quick sketch of part i. yes i know the graph should specifically end at t=4 lol)

## Homework Equations

u(t-a)

= 0 for t>a

= 1/2 for t=a

= 1 for t>a

## The Attempt at a Solution

i'm having trouble solving part (ii).

i remember a friend of mine saying something like "start with whatever the function is at the initial point, then minus what it was, and add what it will become at that particular point 'a' on the t-axis".

i'm not too sure how to put this into an equation.

i have the answer, but could someone please explain how to get to the answer?
