Please assist. I have this Mathematica input
DSolve[{ -((2 Derivative[1][h][t])/c) + (2 h[t]
\!\(\*SuperscriptBox[\(b\),
TagBox[
RowBox[{"(",
RowBox[{"1", ",", "0"}], ")"}],
Derivative],
MultilineFunction->None]\)[x, t])/c == 0 /. b[x, t] -> c/4,
h[t]/4 - (b[x, t] h[t])/c == 0 /. b[x, t] -> c/4, (2 Xi[2][t]
\!\(\*SuperscriptBox[\(b\),
TagBox[
RowBox[{"(",
RowBox[{"0", ",", "1"}], ")"}],
Derivative],
MultilineFunction->None]\)[x, t])/c == 0 /. b[x, t] -> c/4}, {h[t],
Xi[2][t]}, {t}]
But I am getting this output:
DSolve::deqn: Equation or list of equations expected instead of True in the first argument {-((2 (h^\[Prime])[t])/c)+(2 h[t] (b^(1,0))[x,t])/c==0,True,(2 Xi[2][t] (b^(0,1))[x,t])/c==0}.
Help me fix it so that the actual output is a list of equations.
