[tex]{\frac{\partial }{\partial y}}A \left( t,0 \right) ={\frac {\partial }{\partial y}}A \left( t,1 \right) =0[/tex]

Boundary condition

[tex]{\frac{\partial }{\partial y}}A \left( t,0 \right) ={\frac {\partial }{\partial y}}A \left( t,1 \right) =0[/tex]

I don't know how to get this kind of solution. this is my attempt . please help.
