The conjugate comes to the rescue again! (1.3 #75)
To find the limit, we turn to the conjugate once more!
Limits that go to 0/0 (1.3 #53)
Don't fear the "∆x" it works like a single variable, and refers to the change in x.

More Algebra Tricks: The Conjugate (1.3 #52)
Her we take advantage of (a+b)(a-b) = a2 - b 2.
to resolve an indeterminate form.
Using Algebra Tricks to Find a Limit (1.3 #51)

Summer Topic: Domains
Not all functions can take any number. The set of numbers that the function can accept is called a domain. Here we review how to analyze a ...
