(10 points) Can we use the Master Theory on the recurrence T(n) = 2T(n/2) + sin(n)? Please answer YES or NO and then explain your reason. Can we use the Master Theory on the recurrence T(n) T(n/2)+ nsin(n) +2n? Please answer YES or NO and then explain your reason. 6, (10 points) Use the recursion tree method to determine the asymptotic upper and lower bounds for the recurrence T(n) - 2T (+8) + n. 7. 2
