hi BvU and thanks.
you were right this is boundry conditions and they are also incorrect (i am sorry)
3.ψ(x=1,0≤y≤1)=10sin(∏*y)+3y
4.ψ(y=1,0≤x≤1)=9sin(2∏*x)+3x
Homework Statement
i need to solve the laplace equation in square with length side 1 i tried to solve by superposition and i got infinite sum enen thouth i know that the answer should be finite
Homework Equations
1.ψ(x=0,0≤y≤1)=0
2.ψ(y=0,0≤x≤1)=0
3.ψ(x=1,0≤y≤1)=10sin(∏*y)+3x...
