Unformatted text preview: A ( x ) and B ( x ) be series. (a) Using the usual rules from Calculus, show that ( A ( x ) B ( x )) = A ( x ) B ( x )+ A ( x ) B ( x ). (b) Assuming that [ x k ] A ( x ) = a k and [ x k ] B ( x ) = b k , compute formulas for the coeﬃcient of x n in ( A ( x ) B ( x )) and in A ( x ) B ( x ) + A ( x ) B ( x ) and check that they are the same. 1...
