Q.4 Consider the initial-boundary value problem
0 <r<1, t > 0,
U: - Uzz = 6x,
u(0, t) = u(1,t) = 0, t>0,
u(r, 0) = 1,
0 <r<1.
(a) Find a function
boundary value problem
such that u(z, t) = v(x, t) + (a) and
t) satisfies the the initial-
0 <*<1, t >0,
- Vaa = 0,
v(0,t) = v(1, t) = 0, t>0,
v(r, 0) = 1- (aæ), 0<I<1.
(b) Solve the initial-boundary value problem
0 <*<1, t > 0.
- Va = 0,
v(0, t) = v(1, t) = 0, t> 0,
v(r, 0) = 1– (x), 0<r<1.
