Unformatted text preview: a, b ). 4. Using the method of eigenfunction expansion, solve the following nonhomogeneous BV problem: y ′′ + 9 y = 1 + cos( x ) , y ′ (0) = y ′ ( π ) = 0 , given that the eigenvalues and eigenfuctions of y ′′ + λy = 0 , y ′ (0) = y ′ ( π ) = 0 are λ n = n 2 , n = 0 , 1 , . . . , and φ n ( x ) = c n cos( nx ) where the c n are arbitrary nonzero constants. * Instructor: Patrick De Leenheer....
