Hi hope for clear and understandable hand writing
(а)
Given
-1 2
3
A =| 2 1 -1
1 -1
-1 1
4
Find the smallest (in absolute value) eigenvalue using inverse power method. Take
y0) = [0 1 1].
(b)
ди
Given the heat equation
0<x< 4, t > 0 with the boundary conditions
u(0,t) = 1² Int and u(4,t) = r² for t>0
and the initial conditions,
х,
0<x< 2,
и (х.0) -
(4-x, 2<x< 4.
By taking h = Ax = 1, k = At = 0.2 and a =1, solve the heat equation up to second
level using implicit Crank-Nicolson method.
