1 Math 2602 M1/M2 Spring 2007 Additional Problems 9 Generating Functions 1 Tuesday, Feb 20th 1. Find the coefficient of x 10 in (2 - 3 x ) - 18 . 2. Determine the coefficient of x 20 in ( x 3 + x 4 + x 5 + · · · ) 5 . 3. Determine the coefficient of x 10 in 1 ( x - 3)( x - 2) 2 . Hint: use the partial fraction decomposition to see that 1 ( x - 3)( x - 2) 2 = 1 ( x - 3) - 1 x - 2 - 1 ( x - 2) 2 . 4. Determine the coefficient of x 15 in x 3 - 5 x (1 - x ) 3 . 5. Determine the coefficient of x 15 in (1 + x ) 4 (1 - x ) 4 . 6.
