Page 202  208 # 9, 14, 36, 36, 40. 7. Let f ( x ) = sin ( x )2 x + 1 . Find the exact number of roots of f and fully justify your ﬁndings. 8. Let g ( x ) = xe 2 x . Find a formula for g ( n ) ( x ) for a natural number n and then verify your claim with a good proof using the PMI. 9. Let a,b > 0 be constants and let h ( x ) = x a (1x ) b where x ∈ [0 , 1]. Use the EVT to justify that h has an absolute max on [0 , 1] and then ﬁnd this value and where it occurs. 10. Prove that tan ( x ) > x for all x ∈ (0 , π 2 ). NOTE: Reading Week is Monday, July 2 to Friday, July 6, so there are no classes that week. MATA37 will resume on Tuesday, July 10....
