## How do you use the squeeze theorem to find limits?

The basic idea behind the squeeze theorem is the following: If u2200xf(x)u2264g(x)u2264h(x) and limxaf(x)Llimxah(x), then it follows that limxag(x)L. Allow me to explain. f(x) and h(x) form the upper and lower bounds for g(x), as in g(x) can never be greater than h(x) and can never be less than f(x).

## How do you find the lower and upper bound in squeeze theorem?

The squeeze theorem is used in calculus and mathematical analysis. It is typically used to confirm the limit of a function via comparison with two other functions whose limits are known or easily computed

## How do you use squeezing theorem?

## How do you find the upper bound for Squeeze Theorem?

Use the bounds to find limxu221ef(x).

• Notice that the range of both sin(x) and cos(x) is [u22121,1]. An upper bound for both is thus 1, and a lower bound is u22121.
• Clearly limxu221ef+(x)0 and limxu221efu2212(x)0. Thus by the Squeeze Theorem, limxu221ef(x)0.
• ## How do you calculate squeeze theorem?

The squeeze (or sandwich) theorem states that if f(x)u2264g(x)u2264h(x) for all numbers, and at some point xk we have f(k)h(k), then g(k) must also be equal to them. We can use the theorem to find tricky limits like sin(x)/x at x0, by squeezing sin(x)/x between two nicer functions and using them to find the limit at x0.
