Explanation Given: The given boundary value problem is: y ″ = 0 ; y ( 0 ) = y ( π 2 ) , y ′ ( 0 ) = y ′ ( π 2 ) Procedure used: Let L be the differential operator given by the L [ y ] = A 2 y ″ + A 1 y ′ + A 0 y . The formal adjoint of L is the differential operator L + define by L + [ y ] = ( A 2 y ) ′ ′ − ( A 1 y ) ′ + A 0 y provided A 2 ′ ′ , A 1 ′ and A 0 are continuous on [ a , b ] . The Green’s formula: P ( u , v ) | a b = 0 , for u in D ( L ) , for v in D ( L + ) . Here P ( u , v ) , the bilinear concomitant associated with L , is define as P ( u , v ) = u A 1 v − u ( A 2 v ) ′ + u ′ A 2 v Let B [ u ] = 0 represent the boundary conditions required for a function to be in the domain of L and let B + [ u ] = 0 be the boundary conditions required for a function to be in the domain of its adjoint operator L + . Then, the adjoint boundary value problem for L [ u ] = 0 , B [ u ] = 0 is the boundary value problem L + [ u ] = 0 , B + [ u ] = 0 Calculation: Consider the given boundary value problem: y ″ = 0 Here A 0 = 0 , A 1 = 0 and A 2 = 1 . Substitute in the formal adjoint formula: L + [ y ] = ( 1 ⋅ y ) ′ ′ − ( 0 ⋅ y ) ′ + ( 0 ) y = y ″ Apply the Green’s formula: P ( u , v ) ( x ) | 0 π = 0 for all u in D ( L ) and v in D ( L + ) . Apply the formula of bilinear concomitant:

9. (a) Use pseudocode to describe an algo- rithm for determining the value of a game tree when both players follow a minmax strategy. (b) Suppose that T₁ and T2 are spanning trees of a simple graph G. Moreover, suppose that ₁ is an edge in T₁ that is not in T2. Show that there is an edge 2 in T2 that is not in T₁ such that T₁ remains a spanning tree if ₁ is removed from it and 2 is added to it, and T2 remains a spanning tree if 2 is removed from it and e₁ is added to it. (c) Show that a degree-constrained spanning tree of a simple graph in which each vertex has degree not exceeding 2 2 consists of a single Hamiltonian path in the graph.
