The squeeze theorem states if:  Then: Example: The Squeeze Theorem

The chart below shows three functions all converging on a point (0,1)     To find the limit of g(x), use the limits of f(x) and h(x):    ## Alternate Examples of Limits

Example: Factoring and Canceling

Consider the function shown below.  The numerator and denominator both equate to zero resulting in an indeterminate limit. To solve for this limit, the numerator and denominator can both be factored out and we find there is a common term of (x-3) that can be cancelled out, resulting in a form that can be solved for the limit. Example: Multiplying by a Conjugate

Consider the function shown below.  The numerator and denominator both equate to zero resulting in an indeterminate limit. To solve for this limit we will multiply the top and the bottom of this equation by the conjugate of the numerator to remove the square root.   Example: Combine and Simplify

Consider the function shown below.  Both parts of the function do not have a limit at zero. To solve for this limit we will combine the functions into one function and simplify the equation.
