Unformatted text preview: 1cos x  x  and the Sanwich Theorem to show that lim x cos x = 1. Hint: What is lim x (1cos x )? 3 c) For any function f ( x ), if lim x c  f ( x )  = 0, then lim x f ( x ) = 0. THEOREM 5 If for all x in some open interval containing c , except possibly at x = c itself, and the limits of f and g both exist as x approaches c , then Example 12 If lim x 2 f ( x ) x 2 = 1, nd a) lim x 2 f ( x ) 4 b) lim x 2 f ( x ) x Example 14 lim x sin 2 x lim x 1 + cos 2 x 5...
