(c) The solution of the following problem for the wave equation on the half-line:
x > 0, t> 0,
u(x,0) = x, u(x, 0) = 0, x> 0,
u(0, t) = 0, t> 0.
Utt = Urx,
%3D
for x-t>0 is given by u(x, t) =
(A) 히(z + t)2 + (2-1)2 = 22 + P
(B)하-(z +t)2 + (2-기 = -2t
(C)-(z+ t)* - ( - 1}1 = -r² - (D)( +)p - (2 - t)9] = 2xt
