(Section 2.6: The Squeeze (Sandwich) Theorem) 2.6.8 PART B: THE SQUEEZE (SANDWICH) THEOREM We will call B the “bottom” function and T the “top” function. The Squeeze (Sandwich) Theorem Let B and T be functions such that Bx () ± fx () ± Tx () on an open x -interval containing a , except possibly at a itself. If lim x ± a Bx () = L , and lim x ± a Tx () = L , where L is a real constant, then lim x ± a fx () = L . Variations for One-Sided Limits • To show that lim x ± a + fx () = L , we show that

Unformatted text preview: lim x a + B x ( ) = L , and lim x a + T x ( ) = L , and we require B x ( ) f x ( ) T x ( ) on an x-interval of the form a , c ( ) for some real constant c , where c > a . To show that lim x a f x ( ) = L , we show that lim x a B x ( ) = L , and lim x a T x ( ) = L , and we require B x ( ) f x ( ) T x ( ) on an x-interval of the form c , a ( ) for some real constant c , where c < a ....
