i have been trying to solve a pde problem for 3 days but i couldn't even find the answer,now i feel i m about to have a mental disease,anyone can help me ?(adsbygoogle = window.adsbygoogle || []).push({});

the question is

u(x,0) = x

u(x,2) = 0

u(0,y) = 0

d u(1,y) / dx = 0

[ d^2 u / dx^2 ] + [ d^2 u / dy^2 ] = 0

i will really be appreciate if someone help me,for long time i have been working on this

p.s. i have tried for k > 0 and k < 0 but couldnt find anything,the only thing about what happens when k = 0 is we obtain linear equations like F(x) = Ax + B and G(y) = Cy + D,but i have no idea what i wil do in fourier series with these
