@Carl Love

In fact, I should solve the following equation and find the exact solution using the method of Laplace Transformation.

pde := W*diff(C(z, t), z \$ 2) - diff(C(z, t), t \$ 1) = 0
IC[1] := C(Z, 0) = 0;
bc[1] := D[1](C)(0, t) = VMK*D[1](C)(t)/ZRTWA;
bc[2] := C(infinity, t) = 0;

V, M ,K ,D Z, R, T, W, A are emprical constant of the equation.

Thank you once again for your support.

Thank you for taking the time out of your bad day to answer my question.

The correct form of the equation and Bsc7IC is as follow:

pde := W*diff(C(z, t), z \$ 2) - diff(C(z, t), t \$ 1) = 0
IC[1] := C(Z, 0) = 0;
bc[1] := D[1](C)(0, t) = VMK*D[1](C)(t)/ZRTWA;
bc[2] := C(infinity, t) = 0;

V, M ,K ,D Z, R, T, W, A are emprical constant of the equation.

I hope you the best

You are right. The function is "C".

For the second question, yes, D[1](C)(infinity,t) is correct

Thank you for your help.

I posted the question twice as I taught the first one did not work properly.
