Find the temperature function u(x,t)u(x,t) (where xx is the
position along the rod in cm and tt is the time) of a 1818 cm rod
with conducting constant 0.10.1 whose endpoint are insulated such
that no heat is lost, and whose initial temperature distribution is
given by:
u(x,0)={5 if 6≤x≤12
{0 otherwise
To start, we have L=18 0.1 Because the rods are insulated, we will use the cosine Fourier expansion. 22 Ac + =1 A cos(" )e| A cos( u(x,...
