Answer: (a) D i+L divided by g(D), the quotient is z (i) (D), c (i) (D) is the remainder, then D i+L = g(D) z (i) (D) + c (i) (D) ∑ ∑== + = 1 ) ( 1 ) ( ) ( ) ( ) ( K i i i K i i i L D c s D z s D D s ∑= 1 ) ( ) ( K i i i D c s D ∑= ∴ 1 ) ( ) ( K i i i D c s ∑= = 1 ) ( ) ( ) ( K i i i D c s D c (b) Two polynomials are equal, and the coefficient is also same, then the above polynomial equality namely contains ∑= = 1 ) ( K i i j i j c s c...
