Question
Let us consider the following problem for the heat equation
ди
= 0 in (0,1) × (0,+∞),
ốt
u(x,0) = u,(x),Vx E (0,1),
ди
(0,t):
(1)
ди
-(1,t) = 0, Vt > 0.
Use the method of separation of variables to compute the solution of problem (1) if
1)
и,(х) %3D1, Vx € (0,1).
2)
u,(x)= cos77x, Vx e (0,1).
3)
u,(x) = 3+2 cos7x,Vx € (0,1).
4)
u,(x) = sin x, Vx e (0,1).
