Please give me answer very fast in 5 min sini
The PDE
8² u (x, t) – 4 (32
4 (022 u (2,1))
Ət2
where c = 2
Solve the PDE with the initial conditions
can be solved using D'Alembert method. That is, it has a solution of the form
u(x, t) = (x + ct) + (x − ct),
u (x,0) = x²,
ut (x,0) = 3 cos (x).
= 0
Enter the expression for u(x, t) in the box below using Maple syntax.
u(x, t) = (x+t)^2-(3/4)*(2sin(x)*cos(x)
Note: the expression should be in terms of x and t, but not c.
