第 11708 題：邊界值問題

原題與已知條件

內部PDE責任與矩形邊界資料分開。操作=bvp-dirichlet-edge-identity；資料={"coefficients":[-5,0,-3,4,0,0],"bounds":[-9,9,-8,10],"edge":"top","boundary_coefficients":[-35,0,4]}。請依 [bounds,edge,edge_variable,restriction_coefficients,boundary_coefficients,edge_identity,scope] 欄序回答。

定義與適用範圍

沿用原題明示的論域、假設與來源 MKO 定義。本題已完成第二對話數理與中英語義覆核，並由原始參數逐題獨立重算模型、答案與每個算術步驟；原題仍為 candidate。

逐步推導

original coefficients=[-5, 0, -3, 4, 0, 0];basis=[1,x,y,x^2,xy,y^2]

u(x,y)=(-5)+(0)*x+(-3)*y+(4)*x^2+(0)*x*y+(0)*y^2

selected boundary fixed coordinate squared := mul(10, 10)

selected boundary fixed coordinate squared = 100

selected boundary fixed linear term := mul(-3, 10)

selected boundary fixed linear term = -30

selected boundary fixed square term := mul(0, 100)

selected boundary fixed square term = 0

selected boundary constant coefficient := sum(-5, -30, 0)

selected boundary constant coefficient = -35

selected boundary cross contribution := mul(0, 10)

selected boundary cross contribution = 0

selected boundary linear coefficient := sum(0, 0)

selected boundary linear coefficient = 0

selected boundary:vary x;fix y=10;original coefficients=[-5, 0, -3, 4, 0, 0]

ascending x slice coefficients=[-35, 0, 4]

selected boundary coefficient residual0 := sub(-35, -35)

selected boundary coefficient residual0 = 0

selected boundary coefficient residual1 := sub(0, 0)

selected boundary coefficient residual1 = 0

selected boundary coefficient residual2 := sub(4, 4)

selected boundary coefficient residual2 = 0

selected boundary:edge=top;bounds=[-9, 9, -8, 10];remaining variable=x;restriction=[-35, 0, 4];supplied=[-35, 0, 4]

all coefficient residuals=[0, 0, 0];polynomial identity=是
