Hi, I've been trying to solve these PDE below 

Omega*(diff(c(y, t), t))+6*pe*Lambda*(-y^2+y)*cos(2*Pi*x)+pe = diff(c(y, t), y, y)

BC = diff(c(t,1),y)=0,diff(c(t,0),y)=0 

I have got the solution. but could not implement the boundary condition ( maybe those conditions are not correct,/ suggestion needed )

and also have to eliminate those arbitrary constants. pde.mw
