(define (assemble comb nullv t a n b) (if (> a b) nullv (comb (t a) (assemble comb nullv t (n a) n b)))) (define (product t a n b) (assemble * 1 t a n b)) (define (sum t a n b) (assemble + 0 t a n b))

1a) Rewrite the assemble function so it uses tail recursion

1b) Use your newer assemble function to create a function that calculates the factorial

1c) Use your newer assemble function to create a function with the name (ex n k) which computes the approximation of e^x using the following series:
