suppose we have a 2m long rod whose temperature is given by the function u(x,t) for x on the beam and time t. Use separation of variables to solve the heat equation for this rod if the initial temperature is: u(x,0) ={e^x if 0 ≤x<1}    {e^(2−x) if 1 ≤x<2} and the ends of the rod are always 0◦(i.e., u(0,t) = 0 = u(2,t)).

Question

suppose we have a 2m long rod whose temperature is given by the function u(x,t)
for x on the beam and time t.
Use separation of variables to solve the heat equation for this rod if the initial temperature is:
u(x,0) ={e^x if 0 ≤x<1}    {e^(2−x) if 1 ≤x<2}

and the ends of the rod are always 0◦(i.e., u(0,t) = 0 = u(2,t)).
