Hi all,

 

Please help me with this question. I want to solve a PDE by Maple.

restart

A := 5;

5

 (1)

B := 9

9

 (2)

c := 1

1

 (3)

``

eq := diff(u(x, t), t, t)-c^2*(diff(u(x, t), x, x));

diff(diff(u(x, t), t), t)-(diff(diff(u(x, t), x), x))

 (4)

 

dsolve({eq, u(0, t) = A, u(1, t) = B, u(x, 0) = 0, (D(u))(x, 0) = sin(x)}, u(x, t))

Error, (in evalapply/D) too many variables for the derivative of a function of only one variable in D(u)(x, 0)
