Solve the Dirichlet problem in an infinite strip
uxx + uyy=0
for x ϵ R and 0 <y <b ,
u(x,0)=f(x) ,
u(x,b)=g(x). (Hint: first
do the case f=0. The case g=0 reduces to this one
by the substitution y→ b-y , and the case general is
obtained by superposition)
4. Solve the Dirichlet problem in an infinite strip: uxx + Uyy 0 <у<b, u(x, 0) — S(x), и(х, b) — g(x). (Hint: First do the case The case g...
Problem 5: Consider the initial value Dirichlet problem ur(t, x) - 2uzz(t, x) = e, (t, x) € (0, +00), u(0,x) = 1, u(t,0) = e. For the unique solution u(x, t) find the following limit as a function of t: lim u(x, t).
please only use substaction method or method of recflection
