1. The problem statement, all variables and given/known data Question attached 2. Relevant equations 3. The attempt at a solution I'm mostly wondering with c) and also want to check if my solution is correct. My solutions for this question are: u(x,t)= -1/2 for x <= -1/2*t = 1 for -t < x < 1-t = 1/2 for x => 1/4*t+1 lastly, with c), I'm just wondering how to plot 3 space curves on the same axes?(as there are 3 different solutions) thanks in advance.
