Cоnsider the bоundаry vаlue prоblem involving Lаplace's equation in a semi-infinite slab { u x x + u y y = 0 , 0 0 , u ( 2 , y ) = 0 , y > 0 , u y ( x , 0 ) = 0 , 0 0 {"version":"1.1","math":"u(x,y)=Acos(omega x)e^{omega y} + Bsin(omega x)e^{omega y} + Ccos(omega x)e^{-omega y} +Dsin(omega x)e^{-omega y}, omega >0"}where A, B, C, D{"version":"1.1","math":"A, B, C, D"} and ω{"version":"1.1","math":"ω"} are constants to be determined. Part (a): Find ALL values of ω{"version":"1.1","math":"ω"} that produce nonzero solution to the PDE and satisfies ALL the homogeneous BC. Also write their corresponding "eigenfunctions''. Part (b): Write a linear superposition of only the functions in the second answer box in part (a) above to use in part (c). Part (c): Apply the remaining nonhomogeneous BC to the answer you wrote in part (b) to find the function u(x,y){"version":"1.1","math":"u(x,y)"} that solves the full BVP. You must use the answer you wrote in part (b) above to get any credit here.
