u=x and v= are two solutions of the differential equation

such that u(0)=0 and 2v(1)+v'(1)=0

solve the boundary value problem

y(0)=0 and

if u and v are solutions does that mean =u and =v

whats the difference between u(0)=0 and 2v(1)+v'(1)=0 and y(0)=0 and 2y(1) + y'(1) = 0

they have just replaced y=u=v. I will be able to solve this using green's function once I know what are and equal to?

Thanks for any help
