Sandwich theorem is used in calculus and mathematical analysis, typically to confirm the limit of a function via comparison with two other functions whose limits are known.

WebAs x approaches 0 from the negative side, (1-cos (x))/x will always be negative. As x approaches 0 from the positive side, (1-cos (x))/x will always be positive. We know that the function has a limit as x approaches 0 because the function gives an indeterminate form when x=0 is plugged in. Therefore, because the limit from one side is positive ... WebSep 22, 2016 · A (direct) proof to the Squeeze theorem can go like this: Proof: Since a n ≤ b n ≤ c n then 0 ≤ b n − a n ≤ c n − a n, thus b n − a n ≤ c n − a n. Combining the above with the fact that lim ( c n − a n) = a − a = 0 we get: lim ( b n − a n) = 0. spell the end
