Can anyone, perhaps, assist with "1c" below? I have done the part a, but dont know how to go about the boundary conditions required for part c. Your help will be appreciated.

Solve
-Δv = -5/4*π^2*sin(π*x)*cos(π*y/2)
by just modifying the b-vector from exercise part a).
Let the solution be v.
Then add
w(x,y) = sin(π*x)*cos(π/2*y)
to the solution v to get u.
